A cure for aging only needs to get through human clinical trials for treating one aging-associated condition like osteoporosis. Once it has FDA approval for treating that one condition it can be prescribed off-label by a willing physician. If the osteoporosis treatment has unusual side effects of also making skin appear more youthful, improving short term memory, and increasing libido, then there will probably be a lot of off-label prescriptions written a few years later.

So if you have a great way to cure aging but are worried that the FDA does not recognize aging as a condition, that's how you get the treatment to market.

> if you have a great way to cure aging but are worried that the FDA does not recognize aging as a condition, that's how you get the treatment to market

If you have a cure for aging, I'm decently sure you can earn your ROI without respect to the FDA.

Yeah if you cure aging, fuck the FDA, sell it to billionaires for $1B/year until they are broke, then buy congress so you control the FDA
On second thought, you could certainly buy our mostly-geriatric congress with the cure directly, and probably sidestep a bunch of messy FEC regulations
If anyone actually comes up with an empirically verified treatment for aging (let alone a "cure"), market access or payment is not a problem they will face.
David Sinclair is an expert on this and has said otherwise.

Clinical trials are expensive. To fund them you need billions of dollars. Pharmas won’t fund research in anti-aging directly because it’s not considered a disease, can’t get FDA approval, and thus couldn’t be sold.

So, yes, you need to find another route to approval, similar to metformin and rapamycin.

Pharma companies won't fund research because they don't consider the risk-reward tradeoff worthwhile compared to other options for their resources.

Off label use in endemic, and it does give a path to play with some things clinically; however if you formed a company around this idea and could have been demonstrated to do it, you'll be pulled off the market so fast it will make your head spin.

What you are really talking about is about funding the research that wont work, in the hopes that eventually you hit on something that does.

If you do hit on that and can rigorously demonstrate it, market access will not be a problem.

One thing I've never understood, given that trials are so insanely expensive, is why healthcare companies with billions of dollars don't open up "offshore" research facilities to do trials in more lax jurisdictions.

I've done none of the research, just imagining, but if you were to open up a compound in Somalia or somewhere, make the appropriate political contributions, would you really be bogged down with lots of red tape? Could you just experiment and iterate fast enough to develop convincing therapies cheaply and then bring them to mature markets?

So, experiment on poor black people? I think you are on the wrong forum.
The necessary part is only that the prospective subjects aren't protected by strict regulatory regimes like in the United States. Somalia, as, essentially, a failed state, I assume, has lax medical regulations and is a possible candidate for experimentation.

I think it's a bit racist for you to generalize my description of a poor and under regulated state, like Somalia, as being equal to "black people". Not all countries in Africa are like Somalia, you know. I suggest reading a bit more about Africa. I personally enjoy watching YouTube videos made by creators in different countries, African countries have a wide range.

As Mark Twain said, "Travel is fatal to prejudice". Today, we can virtually "travel" with the click of a button. Not all black people are poor Somalis!

The assumption that needs to be true is that experiments without as much regulation are just as valuable as those that have it. I don't know either way though.
> off-label by a willing physician

Just great.

The average age of university presidents and members of Congress in the USA is in the 70s. At the risk of sounding callous can we fix our gerontoctratic system and then fix aging?
Honestly why is that a problem? Wouldn't one thing that we'd want the people with the most experience in higher level management positions.

I don't think the problem with Congress is that members are in their 70s. The problem is that ideally they would have real jobs till their 60s THEN run for government. Instead they bum around various government roles till they get elected in their 30s and once they are there dig in like tics.

Self-fulfilling policy is the best policy.

Also: "...like tic[-tac-toe]

If they intended the insect, "tick" is/was correct.
These sound like two separate problems. That is only 500 people you are talking about. What about the other 7.4B of u s?

Also, they are the ones who are supposed to fix that problem.

I suspect gerontocracy would be a distinct without a difference after someone invents any real fountain-of-youth category of tech (mind uploading included), in much the same way that land ownership went from being a requirement for voting to merely one of many ways to hold wealth as the USA went from an agrarian to an industrial society.

Big difference going from 50 to 70; proportionally less going from 600 to 700, even if the world isn’t changing in a way that makes recent experience count for more than ancient experience.

"land ownership"

A distracting thought: isn't it striking how "real property ownership" has returned as a marker of better societal status? A mere 50-60 years ago, even working class could own (arguably not very nice) dwellings in coastal California etc.

The same development can be seen in Europe.

If I had to choose, I'd rather be an owner of 3-4 nice pieces of real estate than a highly qualified professional. This is a certain return to feudalism, in a sense.

As for your original idea: going from 600 to 700 is not a big deal. But the intermediate phase is going to be a big challenge. The first generation that enjoys the possibility of life extension to, say, 120, is going occupy their positions of power for a disproportionately long time and will need to be persuaded to step away; possibly in exchange for a lot of money.

You know that Simpson's episode where Bart lines up a bunch of megaphones so that the amplified output of each one goes into the input of the next? Obviously in the real world the sound would saturate. Exponential amplification would stop after one or two megaphones as a few tones would "win" and suppress the others. The joke is that in the cartoon world it keeps on going and turns into a sonic tidal wave and we all laugh at the idea of ten megaphones producing a sonic tidal wave.

Yet when we design an economic system by the exact same principle, people wonder why we get ten shrieking megaphones instead of a magical tidal wave.

But if we extend life then we can have these wonderful rulers for even longer.

Edit: I forgot HN does not enjoy sarcasm

My favorite response to this and related objections to ending aging (such as “what about the dictators”): imagine a scenario where humans did not age, but still had the problems of “gerontocracy” and dictatorships. Would you propose subjecting the whole of humanity to debilitating degenerative diseases and ultimately death to solve these societal problems?

I picked this up from Ageless by Andrew Steele, a highly recommended and very current overview of the field of aging research.

I've never considered this question before, but if people did live forever, requiring people in certain positions of power to be subject to some sort of incurable, debilitating disease or guaranteed death seems like a pretty reasonable safeguard to me.
If people live forever except for those in power, and power is opt-in rather than, e.g., sortition, power can only go to people who prefer it over eternal life.

That group will be composed of the insane/irrational, those who value power at extremes, those who value improving the world over their own lives, and those who have lived long enough that they're ready to move on. The last two categories are great candidates for empowerment, but one is rare and grows rarer, and the other doesn't show up for upwards of centuries. Until then you mostly get the first two, which suck. Eventually, I think, we burn through everyone willing to make the trade-off and we're left with no power centralization.

Unless you mean they only face death for the duration that they are in power, as an enforcement of term limits. I don't think that is materially different from other enforcement of term limits- if a dictator is able to compromise the military, they can probably also compromise whoever has the power to stop their impending death.

... yes? Preventing immortal dictators is absolutely worth keeping death around.

It's hilarious to me how shortsighted this whole thing is, if immortal dictators rule humanity indefinitely, how long do you think they'll let you live?

I think "those people would be assasinated more frequently than they are today" is a much more plausible outcome than "subject all of humanity to debilitating degenerative diseases."

At the country-level scale, that certainly sounds better than everyone aging and dying.

But what would individuals do on a smaller scale? Would this also incentive a lot more violent death among the rest of the population too, to change things up in a world where probably everyone is their own long-lived dictator of some little domain they carved out. Sure, this would be illegal, but you can only catch and prosecute so much crime; what if it becomes unmanageable? Would people create unnatural death to serve the role natural death causes today? I think so. But I think this could still be potentially "better" than today in some measure - you're comparatively healthy and pain-free before your demise, instead of a slow painful decades-long decline.

If you live forever, committing crimes seems like it carries a larger risk. Including a much higher risk of actually being murdered, in prison.
Oh the other hand, consigning yourself to death via assassinating a hated despot seems better, morally, than consigning everybody to death to make them die of old age.
My suspicion is that space travel will become a necessity if we end aging. People will have to move to new worlds to escape the ossified social/economic hierarchies. Kinda like how in the Enders Shadow series they send all of the Battle School alumni to different planets cause Earth can’t handle all of these military geniuses.
Yeah it seems like the same thing as proposing we shorten today's average lifespan from 80 to 50 as a solution.
This seems like a loaded question. How would the people in power allow someone else to make that decision? If the issue still exists and there are no alternatives (implied by it still existing), then what would the eventual answer be? It seems that the power dynamics would not allow for artificial control and thus, some natural control for which the people in power have little influence over would be necessary.

I kind of like somthing along the same lines as the idea intended in Altered Carbon - everyone gets 100 years of generally healthy life, but then everyone dies at 100. Not realistic at all, but seems highly equitable. Any artificial constraints will be evaded or manipulated at some point, even in the name of what's best for humanity (ie what if Davinci or Einstien were still alive; eventually the people in power would say I'm president, so presidents should live forever too, etc).

Regardless, the bigger issue would be overpopulation.

OK. Do you want to die? I don't want to die.

Life is already inequitable as it is. The rich live a little bit longer. The pleb dies short and miserable life.

At the very least, everyone should be able to live as long as they like.

Any artificial constraints will be evaded or manipulated at some point, even in the name of what's best for humanity (ie what if Davinci or Einstien were still alive; eventually the people in power would say I'm president, so presidents should live forever too, etc).

There's also no absolute law of politics that dictators rule forever or indefinitely if they also happen to be immortal.

Regardless, the bigger issue would be overpopulation.

No, the problem is ecological disaster.

There's so much energy coming from the sun that humanity can't even begin to harvest a fraction of it, but we cannot scale to the sun because doing so will poison the Earth.

"Do you want to die?"

Someday, yes.

"Life is already inequitable as it is."

Which is why my statement was commenting on the equitable nature of lifespan in the fictional system.

"At the very least, everyone should be able to live as long as they like."

How do you propose to achieve this? Specifically, how would resource availability/consumption and indignant support systems be able to support it?

"There's also no absolute law of politics that dictators rule forever or indefinitely if they also happen to be immortal."

Nobody suggested what you are saying.

"No, the problem is ecological disaster."

For which increasing population would greatly contribute. Population is a major driver of consumption and there's no evidence that we can even support our current population sustainably. Your comment about scaling seems to be implicity acknowledge this.

I might not have the heart to but a rational agent acting in the interest of the entire population would. In fact this is basically what natural selection did to us. If much longer lifespans would have benefited our species we would already have them.

It turns out that the way out brains crystallize as we age and make us better at teaching but worse at changing our minds means our ideal lifespan is not very different than the ones we have. I know individuals can work very hard to avoid this outcome but most people don't.

Natural selection doesn't act upon humans for the sake of humanity, nor did it ever asked what humans want or need.

Citation? I would argue that adults are better at learning languages, because we have the benefit of hindsight, experience, and reasoning.

Whereas children are merely subjected to immerse learning environment from which to acquire languages pretty much every waking hours of their life.

Imagine being fresh out of school, competing in the job market against a huge pool of people who have been working for a century. Now that I think of it, though, what's the difference between a gerontocracy and hiring the most experienced senior candidates? Is it just government vs private sector?
Imagine going to school for 50 years? You're still a child at 100? Imagine being able to use compounding interest for a hundred years before you start work. I do not think we can approach this world with our current perceptions.
The biggest concern I have is that with current societal expectations an infinite life span would mean working for thousands of years for someone else with little to no retirement phase of life. Effectively, infinite slavery. No, we require major societal change for this to be attractive.

Regards compounding interest, the economic markets have a basis in reality and so can't keep compounding forever.

Also even if it does compound forever, your trifling savings compounded for 100 years means very little compared to all the elder around you who have also compounded their much larger wealth(having compounded across previous centuries too) across that time. Which means you will still be significantly outbid by most of the customer base for anything you could want.

> No, we require major societal change for this to be attractive.

I agree. But unfortunately my understanding of history suggests that cultural and political change is reactionary, not forward thinking. I'd love it if it was forward thinking but I'm not hopeful that this time it'll be different. But if I'm right (and I think most people will agree) then there's no real point to this aspect of the argument because it's not something we can solve.

> Regards compounding interest, the economic markets have a basis in reality and so can't keep compounding forever.

Do you have evidence of this? This is essentially what generational wealth is.

> your trifling savings compounded for 100 years means very little compared to all the elder around you who have also compounded their much larger wealth

I have a bit of a controversial opinion on this (though I'm not sure why). I don't think it is about how far the ladder goes up, I'm more concerned with where the lowest rung is. If moving the lowest rung up requires shortening the ladder, so be it. But if it doesn't, so be it. If you can have a house, food, healthcare, and all your basic needs taken care of (which I presume will continue to increase as we take care of more needs. Moving goal post) then that is a win. I don't care how high the ladder goes if the lowest rung is post scarcity. If every person can has all their needs taken care of I don't care if there's a few x-airs that have quantum space yachts with holodecks. You don't have to compare yourself to everyone else. Everyone doesn't need to be equal. That's not a requirement to create a post scarcity world where everyone can pursue their dreams without worry of hunger or health. Inflation adjusted, food has become become a lot cheaper over the last hundred years, so at least one of those things is on the right track. What we're talking about would put healthcare on the right track (especially if you're pro single payer). Seems the other ones will similarly decrease in price as they become necessary (again, back to the reactionary nature).

Maybe you disagree though. But as long as there are people, like you, pushing for these things, I have good reason to believe we will obtain them.

Your controversial opinion is not bad as a vision. But I don't think it would work out that way unless aforementioned significant societal changes occur.

As a newcomer, you won't be able to buy a home. Similar to now, there will be many other more wealthy people who want to buy that home "as an investment" so they can keep growing their wealth in relation to their peers.

I already fear we are heading towards economic feudalism. Throw in living forever and I fear something more akin to SLA Industries: https://en.wikipedia.org/wiki/SLA_Industries

As you say though, with people pushing for things, hopefully significant societal change would avoid such a disastrous future.

edit - more concise.

> Effectively, infinite slavery

I’m really sick of people equating working for someone else with slavery.

Disclaimer: this is a non-partisan comment. Both parties are reflected below.

It makes me wonder if the US system will break down the same way the USSR broke down. As the politicians from the "early days" age out, it's difficult to replace them with people who are similarly bought into the system. And you end up with a Gorbachev or equivalent. I'm not sure if our Gorbachev is an AOC-like or a Trump-like or something else, but it's possible we'll have difficulty filling in the ranks of the Pelosis, Schumers, McConnells, etc.

What if experience is beneficial at such positions and fixing aging would benefit us even more? Imagine if Einstein and Newton each lived for 400 years and met each other.
"the WTP at birth for the initial 1-year increase in remaining LE from 78.9 to 79.9 years via rectangularization is US$118,100, the WTP at age 60 for the first 1-year increase in remaining LE from 21.7 to 22.7 years through lifespan improvement is US$257,700."

Who the fuck did they get to determine willingness? Most people don't have the money to spend. If it takes you years of extra work to pay for a one year life extension, why not just retire years earlier and enjoy that time? After all, you could still die from an accident after paying the sum at birth/60. It seems highly inappropriate to use a population based metric like life expectancy to have individuals decide if they want a one year increase (likely the individuals don't understand life expectancy as well as).

At a guess, old people have a house or something they can sell for that much.
Given the massive gap between what people should have for retirement and the little they actually save, they probably need that money for necessities. That's what most people using reverse mortgages use it for today.
Back when I was _really_ into longevity stuff, aubrey de gret etc... I seem to recall that even if we removed all forms of aging people would have an expected lifespan of roughly 1000 years due to trauma death (eg: getting hit by a bus) . So that could serve as a rough rule of thumb for how to think about risk/reward on increasing health in later years. That is it generally has a good EROI for how safe (accident wise) our society actually is.
If you don't mind me asking (off-topic), are you less into longevity stuff now? if yes, what made you less into it/possibly more skeptical of it?
Not the same person, but it used to excite me when I was younger. Now I realize that life is mostly full of bullshit outside our control. I hate my job, so why would I want to live significantly longer when it means working longer? Political and cultural changes could be difficult to handle too.
I sometimes have similar thoughts, but then I wonder, if I were to live to 300, maybe some of the bullshit would go away some time in my 100s and everything might be more enjoyable?

Let's hope we don't need to deal with critical race theory / unconscious bias trainings at work and open derogatory statements against non-minorities for more than another 5-10 years, for example... I have to say it's making work a lot less pleasant than it used to be.

And maybe if we're extremely lucky some of the VC money will become more widely available to people based on competence rather than connections and personal wealth.

If other people are living to 300 too, then I would think it's likely they will bring their bullshit with them, right? I feel like dying isn't just about making physical space for then next generation but also allowing space for cultural changes.
Climate change is also going to make the world increasingly less pleasant to live in over the next couple decades, directly (weather, flooding, drought, famine, etc) and indirectly (instability, social unrest, war). Unless you can extend your life long enough (and otherwise have the means) to see the other side of this epoch, suffering through more of it is probably not desirable.
(comment deleted)
honest question, do you think this is true even for middle class or wealthier people from wealthy nations? I imagine we have the resources to just move and adapt.

The way I understood it it's the poor nations that are really screwed. They cannot afford to relocate, and some of them have the worst weather already (feeding into why they're already poor).. .

Sure, the wealthy will be able to move and adapt, consuming an increasingly large share of the dwindling resources to maintain their comfortable lifestyle. Meanwhile the poor and then the middle class will be left to fend for themselves, or stuffed into refugee camps in marginally habitable areas.
... or rise up as history has previously shown.
Presently I am less into it because I realized a few things

1. A lot of the things are either very expensive or very difficult. Ex: the probiotics david sinclar takes is like hundreds of dollars, NAD/NMN are expensive etc. Other things are difficult for my current life like getting access to heat exposure therapy (very hot dry sauna) or fasting protocols. Inside tracker with inner age is like $600 each time?

Also I realized that if I donated to methuselah foundation, I'm investing money into the future for others' treatments I'm unlikely to be able to afford myself (or marginally worse, I would have been able to afford, but I donated $$$ over time such that I marginally no longer could..)

2. There was little point looking at the extreme ends of longevity because I was missing major first steps like dropping my BMI from 31 to 23.

Sure, it's generally safe. The point I was trying make is why work extra years to pay for a single year when it's not guaranteed. I'd rather quit at 60 and die at 78 than pay $200k, quit at 64, and die at 79.
ah, that makes sense. Basically guaranteed vs less than guaranteed.

But some percent of the population makes a lot more than that. And much like all things in the economy as they start to consume the products it gets cheaper and moves down classes until it becomes ubiquitous kinda like food is today.

When I did construction, many conversations were about the generous retirement benefits.

It was always, "When I retiree I will be able to do this, and that, in comfort."

There was always the big decision of shouid I retire at 25 years (25 year old working 25 years), or get a few hundred more if I wait until 65?

I knew a person who worked accounting at the union.

She told me the average retire whom waits for the bigger pay day, cashed 3 checks.

3 checks----dead. (I was so shocked by this I never told anyone including my father.)

The wives did get 1/2 of the retirement, and lived off that for 10-20 years.

(I guess I should have been content with any work that offered a retirement?)

Yeah, I've seen some studies that link early retirement to earlier death, but also some that show retirement can trigger underlying issues like stroke and heart attack from the changes.
Anecdotally similar happened to my step-father. He was working extra shifts, overtime etc. Died 6months before full pension. He never cashed a single check and my mom only got about 1/2 of what the full pension would have been worth (discounted value) because he passed "before retirement" .

This is part of why I'm so adamant that I think pensions and the like are scams. I want to run my portfolio and my next of kin can have every cent (less taxes)

Yeah, that does suck. My grandfather did earn a pension and retired from the steel industry. The company went bankrupt and he got maybe a quarter of what he was supposed too and he was one of the lucky ones. Many others didn't get anything.

It would be nice if companies paid more into the 401k though, and didn't necessarily require the match. The 401k system is also letting companies off the hook with measly amounts. I'm mostly thinking about the people working at places like Lowe's and Walmart making $10-15/hr. Even 4% of $30k is only $1200 per year. Some of the people I knew who were working there were only contributing 1-2% (so 2-4% total with the match) because they couldn't afford to contribute more.

i mean, I dont think companies should be on the hook. Instead I think that money should just move into regular compensation and the government should be the one to both allow and incentivize 401k usage.

It's kinda weird that I can only contribute $19k but if my company matches more can go in? That makes no sense. The limit should be the limit regardless of the graces of your employer.

I'm willing to bet that we're also going to get significantly better at treating trauma within that thousand years though. The numbers aren't great now, sure, but what about in something like 500 years when we can begin doing complex tissue engineering and replacing parts of the CNS? There are certain things that no amount of medical advances will solve, sure(Not really much to replace after your liner to Mars explodes), but I think that if we found a way to cure aging tomorrow, most people would live well beyond 1000.
I know some really spry older (60-80) people. Good diet and exercise is what they have in common.

It also helps with mental health (which we have an epidemic of in the US).

By all means, this research should continue. But we do already have very good solutions to aging which are sorely overlooked.

The general Aubrey de Grey response to this observation is that yes, lifestyle improvements are great and diet/exercise are great for improving one's life. However, it ends up conferring only a few more years of life. Some evidence he provides is that even very healthy (by obesity metrics for example) countries only have a life expectancy a few years longer than "unhealthy" countries. I think he cites like Japan (with lower obesity rates) having a life expectancy of 6 years longer than US (high obesity rates).

Not my observation so feel free to caveat me away, but I'm just regurgitating what some doctors who studying aging observe and perhaps I'm not remembering all the evidence they provide.

This reminds me of some articles that came out when the states sued the tobacco companies in the 1990s. Many asked why the US federal government did not sue as well, and the answer turned out to be that smoking is good for the federal government finances. It tends to kill people quickly (heart attack) just after they retire and start collecting social security.
Not surprised David Sinclair is one of the co-authors. Anti-aging is a fascinating new field. It's great that there's some discussion about economical aspects of "slow down aging" at a large scale.
It’s obvious that healthy people that live shorter are better for the ‘economy’ but clearly humanity doesn’t live to optimize for the economy. If we did, we would be fighting obesity with 10x the seriousness of how we fight COVID.
basically anything that wasnt a long term compounding investment would be illegal... Obvious things like smoking and vaping, but maybe even time wasters like social media (you could be learning something...)

Luckily human life is more than just economy (as expressed in GDP) optimization.

(comment deleted)
There is no cohesive "humanity" with any sort of desire or ability to optimize for "the economy."

Individuals optimize for their own (often short-term) economic benefit. That's it.

The corporate overlords at ACME don't care about fighting obesity, because there are more than enough non-obese workers for them to exploit, and they don't want to cannibalize their highly profitable line of products that obese people need (i.e. insulin).

Governments are composed of individuals, and the structures we have to hold these individuals accountable to their constituents are weak, so they still end up using their levers of power for their own gain, and for the gain of their corporate sponsors (also often short-term).

Despite ~70 year lifespans, it seems that most of the population can't even be bothered to optimize for medium-term outcomes. This isn't going to change just because we invent a magic pill that lets you live youthfully till ~150.

The problem isn't lifespan, the problem is that humanity is innately selfish and short-sighted. If this can't be fixed, we are completely fucked.

> Individuals optimize for their own (often short-term) economic benefit. That's it.

Don't go to too far with this sort of atomistic analysis. Large firms are better at enforcing coordination than "society at-large" or other groupings. The fact that at different scales the coordination is markedly different has a huge affect.

We're not an "economy of households" as the orthodox macro might have one model.

> Large firms are better at enforcing coordination than "society at-large" or other groupings.

The "large firms" that I'm familiar with are cesspools of political infighting, gamesmanship, and backstabbing. People in positions of power at these firms use their influence to achieve their own goals, often at the expense of the firm and its employees.

The counterexamples to this are so singularly rare that they are the exception that proves the rule.

It's still miles above the e.g. non-interaction of neighbors in the same cookie cutter subdivision.

The fact that people fight over how to divy up a budget vs have completely separate revenue and accounts says a lot, despite all the stuff you talk about.

> humanity is innately selfish and short-sighted. If this can't be fixed, we are completely fucked.

The communists tried pretty hard to do that, and just made things much worse.

This is an incredibly important fact that is often downplayed.

We remember the Inquisition and the Vikings but they are small fry compared to Communists (and Nazis).

I'm not saying Communists are inherently evil - most of them are well meaning I think - but almost every single time it has been tried it has ended in genocide!

The one single exception I am aware of is the Israeli Kibbutz system.

Edit: communism has killed more people than nazism, probably because most people realize nazism is more or less pure evil while communism looks nice (edit:) on paper.

The Kibbutzen don't work, either. The Israeli government taxes the capitalist businesses in order to subsidize the deficits of the Kibbutzen.
What's the cost burden to Israel of the Kibbutzen vs the cost of supporting the ultra-conservative religious groups that don't serve in the military and rely (presumably) more heavily on welfare and other social subsidies?
You are probably right. And that is a good point too, it fails economically too.

My original point was only that the Kibbutzen didn't end up massacring their inhabitants like almost every other communist experiment.

The linked abstract claims the opposite: "We show that a slowdown in aging that increases life expectancy by 1 year is worth US$38 trillion, and by 10 years, US$367 trillion." Is saying the opposite is just "obvious" enough of a rebuttal?
(comment deleted)
A slowdown in aging is a ‘healthy person’ being given more time.
I'm not sure that's true. We invest a lot of money in making people productive at their jobs, basically 0-25, and then they only work another 40 years after that. If they could work another 60-80 years instead, the return on investment is much better.
I think he means under the current life expectancy and quality of life in the final decades.

He probably means those final decades are completely unproductive and taxing on the whole economy, so a productive person dying just before becoming unproductive would be optimal.

Naturally, if you give people more productive years then it changes.

(comment deleted)
It's strange. Obesity is our biggest preventable health problem, and it gets almost no attention in the media or by public officials. We heard endlessly from health officials and news media personalities to wash our hands, stay indoors, wear a mask, get vaccinated, but nothing about eating healthier, eating less, exercising more?

"Obesity steals more years than diabetes, tobacco, high blood pressure and high cholesterol -- the other top preventable health problems that cut Americans' lives short, according to researchers who analyzed 2014 data."

"Obesity is associated with nearly 1 in 5 US deaths, according to a study published online August 15 in the American Journal of Public Health."

https://www.medscape.com/viewarticle/809516

It should also be part of the climate change discussion:

"Overall, being obese is associated with about 20% more greenhouse gas emissions (carbon dioxide, methane and nitrous oxide) than being a normal weight"

It's strange. Obesity is our biggest preventable health problem, and it gets almost no attention in the media or by public officials. We heard endlessly from health officials and news media personalities to wash our hands, stay indoors, wear a mask, get vaccinated, but nothing about eating healthier, eating less, exercising more?

Because it's been going on in the background so long, that it became part of the background.

Also, it's not like it's not noticed by public officials. You hear all the time in recommendations and guidelines we should lose weight and get more exercise.

That said, I would also note that current public health policy is basically a failure in that we largely failed to move the needle regarding the obesity pandemic or getting the recommended exercise dose.

> recommendations and guidelines we should lose weight and get more exercise

We also don't understand it, not well at least. You can't go to Walgreens, get a shot and be cured of obesity.

What part of obesity is not well understood?

Societies with easy access to calories and sugar/carbs/sat fats and reduction in movement and increase in sitting have more obesity, right?

Societies with easy access to calories and sugar/carbs/sat fats and reduction in movement and increase in sitting have more obesity, right?

I am doubtful that easy access to calories means more obesity. The Japanese is a wealthy society and is less obese than the American, for example.

Also, societies that move more doesn't necessary have an increase in TDEE as society that move less. Your basal metabolism adjusts and accounts for physical activities. you would probably need to go to extreme to adjust your TDEE upward.

I’m sure there are cultural and genetic components also, but you can simply compare parents and their children over the past few decades in countries with obesity problems to control for some of that.
It would be a great experiment to ramp up sugar taxes on certain parts of the country and see weight change over the decades.
Really? There are multi-billion dollar industries catering to the obesity issue - health food, supplements, exercise equipment, exercise gurus. Employers offering incentives since it leads to lower insurance costs. In the USA, health food options have grown tremendously in the last 10 years, but at the same time obesity has gone up.
All of those are useless. But profitable. As long as they don't solve the core issue, which seems to be in the brain.
> It's strange. Obesity is our biggest preventable health problem, and it gets almost no attention in the media or by public officials.

I have seen many, many reports, news specials, CDC website reports about being overweight and obese driving increases in health risks. Michelle Obama, as First Lady, was on top of it and reformed the food pyramid nonsense.

Because, like alcoholism, it's a choice. If you force people to lose weight, why not force them to stop poisoning themselves.

Of course, it's all a bunch of hypocritical bs when other, safer, more useful drugs are banned or restricted for stupid reasons.

I only skimmed past the abstract (wolverine case is gold, lol) feel that such an analysis gets squirrely, both morally and technically.

A few years back, there seemed to be a desire to justify cigarette taxes with a "it costs the state money when you get cancer" rationale. Some of the analysis seemed to indicate opposite results. Lung cancer, for example, tends to kill more quickly than age related diseases, saving on nursing home costs and palliative care. Everyone dies of something after all, and death is expensive as is aging.

Either way, it seems kind of strange to place economic values on life itself. I mean isn't economic utility premised on life?

In any case, it seems trivially true that economic measures will always correlate with either population size working age population size, depending on the model.

I feel like these kinds of papers only exist to be cited in support of cheap rhetoric.

"I feel like these kinds of papers only exist to be cited in support of cheap rhetoric."

Agreed. The authors already made up their mind regarding the conclusion before writing the paper. This is an analysis that should be done by a group not involved in aging research so it's 'unbiased'.

Any action you take to preserve life has the side effect of putting an economic value on life.

You invest some amount of effort into the action and the action has some amount of efficacy, so you can always divide the two to find a valuation. I agree that this exercise usually winds up as cheap rhetoric, but I'm not fully convinced it's the fault of the exercise.

Refusing to calculate a value doesn't mean the value doesn't exist, it just means we are letting our instincts decide the value for us, and our instincts are prone to doing silly things like spending the wrong amount of attention on anti-terrorism vs heart disease.

This has a "trolley problem" feel to it. It's a contrived scenario that doesn't reflect real life.

I'm not suggesting that all our decision making is good. Terrorism vs heart disease just don't really compete. A model of the world where everything competes with everything isn't a good one for decision making. Just like "don't build a particle collider until we have solved poverty" is not a workable approach.

Terrorism & heart disease don't have the same consequences, socially, politically or geopolitically. We're not machines. Even in machines' decision making, such moral calculus doesn't really play. Self driving cars won't, and don't need to solve the trolley problem any more than we do.

..and don't underestimate our instincts. They may not be as "perfect" as legible reasoning, but they are far more complete.

> It's a contrived scenario

Any time you help people is a contrived scenario? Uhh... I certainly hope not. Putting a valuation on life is not a result of philosophical debate, it's a direct, unintentional, unavoidable consequence of any real-world action we take that helps people. The only way to avoid it is to avoid helping people. Which is ludicrous.

> Terrorism vs heart disease just don't really compete.

They sure compete for tax dollars and public attention.

> We're not machines.

No kidding. That's why we prefer chasing Bin Laden to chasing heart disease.

The "value of a life" discussion is an accusatory finger that says "yeah, actually we did have a choice there, and our choice had consequences," and I understand how that's uncomfortable, but that's exactly why we need the tool to hold our instincts accountable, such as we can.

No, the trolley problem (an example used in moral philosophy) is a contrived scenario.
> Terrorism vs heart disease just don't really compete.

They do actually. Both for budget and for misery.

> A few years back, there seemed to be a desire to justify cigarette taxes with a "it costs the state money when you get cancer" rationale.

When you have guaranteed pension funds for an ever growing number of bureaucrats, you HAVE to find new ways to tax. Taxing unpopular things is the easiest thing (and doesn't hurt for reelection).

Tobacco tax does not make or break any budget, at least not where I live. It is also taxed with the intention of reducing sales, which in turn reduces tax income. This is also by large the result.
There are a lot of DIYers experimenting with senolytics and Rapamycin therapies for longevity. I expect that in the next 10 years or so evidence will be clear that at least some of these therapies work. It will be undeniable as more and more people start to hit their 80s, 90s, and beyond in very good health.

I'm in my 30s so not in need yet but I'm keeping a close eye on the science.

For example, this clinical trial [0] is studying the safety of various dosing schedules of Rapamycin, and a planned followup study will use the safest dose with a larger group and longer timeline.

> I expect that in the next 10 years or so evidence will be clear that at least some of these therapies work.

It's an interesting area, and at least some empirically useful work is being done, but both the expectation and the timeline here seem pretty ambitious.

They're not DIYers when using a prescription drug. Something inaccessible to the majority of the population.

Can't wait for a time when trying to delay your death requires serious justification and approval from some asshole whose only authority comes from 5+ years of overpriced formal education.

Sortof. But the assholes do know a bit about science, and are taking an arguably conservative view on pharmacological interventions in the treatment of aging to prevent possible problems. For example this trial: Targeting the Biology of Aging. Ushering a New Era of Interventions. The official web resource of the TAME Trial, managed by the American Federation for Aging Research.

they are not saying that taking metformin slows aging, merely that it delays development of chronic illnesses. What we should be asking is if metformin is actually slowing down the biological aging process. https://www.afar.org/tame-trial

I'm skeptical of miracle cures. The increases we've seen in life expectancy over the last 100+ years has more to do with eliminating low-hanging fruit - e.g. smoking, vaccines, eliminating infection, diagnostic technologies and treatments, etc. I think we'll continue to make incremental gains via this approach such that avg life expectancy inches up by single digits for the foreseeable future.
Maybe conservatives worrying about death panels in 2008 weren't so crazy...
The quest for immortality is popular, but it would mean the end of physical and cultural evolution. Seems as though this topic is gaining steam now, only as a large corpus of aging narcissists are finally grappling with the concept of death. It's another sign of the selfish immaturity ingrained into our culture.
This is nonsense. We change everyday through forgetting and remembering and learning. Physical and cultural evolution don't stop.

It's another sign of the selfish immaturity ingrained into our culture.

Selfish immaturity? It seems that you yourself is a reflection of culture.

One of our very first epic poems, the Epic of Gilgamesh basically railed against immortality and accepting one's fate.

> Physical and cultural evolution don't stop.

If someone lives forever, they don't evolve physically. This is basic. To the degree we evolve culturally, most of our culture comes to us in our eponymous "formative years." Leaving those behind tends to result in comparatively little change in culture over the remaining course of our lives.

> Selfish immaturity? It seems that you yourself is a reflection of culture.

I rest my case.

> One of our very first epic poems, the Epic of Gilgamesh basically railed against immortality and accepting one's fate.

This was not a call to try and live forever, this is a call to live boldly, take risks and not to fear death. Striving for immortality is the absolute opposite, the coward's response to the challenge made in the poem.

> If someone lives forever, they don't evolve physically.

you skipped some lessons in biology class; you're not doing any evolving over the course of _your_ life. regardless of how long or short it is.

Evolution, by definition, occurs over the course of generations. So angry and yet so wrong.

If a population lives forever, do you really think they'll continue having kids the entire time? Of course not.

Please feel free to end your life at your convenience, billions of others will take the opportunity of living for as much as possible.
This is not an appropriate comment for HN.

That is not a law of physics or biology. People get heart implants, or even exercise and become stronger.

I rest my case.

Rest your case how? You didn't demonstrate that it is selfish and immature to desire to live, perhaps indefinitely.

This was not a call to try and live forever, this is a call to live boldly, take risks and not to fear death. Striving for immortality is the absolute opposite, the coward's response to the challenge made in the poem.

I assure you that I do not make conscious decisions about whether I live a thousand years if I undertake a given activity. I am also pretty sure that I routinely undertaken relatively dangerous activities that would kill me.

I doubt most people who becomes immortal will become the sort of conscious decision makers deciding not to take risk lest they jeopardize their thousand years+ lifespan. That doesn't seem to jives with human nature.

I am constantly attempting to improve myself. Sometimes, I wonder if I will finally achieve perfection only to run out of time and die :-/

There's a heluva lot I wish I could tell my 20 year old self. Sometimes I counsel my friends in their 20s, but they don't believe me, as I didn't believe this stuff in my 20s.

I second your thought. For sure, I am smarter and wiser then I was in my 20s, which wasn't long ago. But I am also carrying baggage of the past with me, which in some case makes less wise and less brave than I wanted to be.
> There's a heluva lot I wish I could tell my 20 year old self.

Like?

(comment deleted)
The bandwidth on that connection isn't great. You can't fit 20 (or 40) years worth of experience through the narrow tube of spoken language without massive compression. A single sentence can stand for years and years of trial and error. Or it could stand for nothing but frustration and regret. Young people have no context or wisdom or experience to relate to. So it's kind of impossible.

Likewise it is impossible to communicate what 20 years of adult experiences feels like to someone who is barely an adult; not all years are the same. And then when they get to 40, likewise, communicating another 40 years of life experience to them doesn't work either. Growing up and aging can only be done first hand.

Compound this with the fact that some old people are just dumb and angry. So young people can and should just shrug off some of what old nutters say.

I'm reminded of Nick Bostrom's story called "The Dragon Tyrant"[0][1] and David Foster Wallace's "This is Water"[2]. The dragon became so normal in our lives that we do not even question it, like a fish does not question what water is. That we've created a society around this how to deal with this inevitability. But at the end of the day if we could, killing the dragon would be more beneficial and reduce harm by a significant amount.

I see several people in this thread complaining about the economic analysis here or how old people are messing up our world and thus we should fix those things first. For the former question, I see this analysis as adding ammunition to the debate, because many people that determine where we should fund base their decisions on economics. This paper isn't aimed at you, it is aimed at them (speak to your audience). For the latter, I question the premise. Culture has moved too fast that it cannot be purely explained by younger generations dictating the change. This also falls counter to old people controlling everything. So I don't buy the premise. The truth is that if people were living to a thousand years old that society would fundamentally change. Who we consider children and adults would fundamentally change. The truth is that we don't know what this society will look like until we open the box, and until the dust settles. We should be questioning if this is good or bad (we should challenge all ideas) but we need to recognize that this would be such a fundamental change in society that we have no real baseline for determining how we would change. My personal belief is that we do not go quiet into that dark night. There is a lot to fear, but often our fears are irrational. This would save billions of lives, and so I believe it is worth the risk and worth the hardship we will face as society transitions into this new paradigm.

> My personal belief is that we do not go quiet into that dark night

I think many do. One of my takeaways from the pandemic is that there are people--intelligent, informed, unoppressed people--who will self select away from benefits. Even seemingly obvious ones.

The fictional dystopias of the last century would have had an immortal elite keeping aging treatments from clamoring masses. I don't think that's how it would turn out. Many people--including leaders--would choose not to get the treatment. Still others would push their societies to ban treatments for everyone.

I don't know how you model this. It's a different form of haves and have-nots than we're accustomed to. But it would undoubtedly feed into and ameliorate the concerns brought up in this thread.

Or those who prefer not to (for whatever reason) may be categorized in a way similar to the way we treat the suicidal. Anyone unwilling to attempt to live forever would be considered mentally ill.
That would require them to be a small minority, which the OP is suggesting would be the opposite of the case.
I guess it depends on the validity of the arguments put forth in Ernest Becker's The Denial of Death.

The important distinction between longevity and the situation surrounding the pandemic is not the rejection of a benefit, but the construction of a fantasy that allows the rejection of the benefit by re-framing it as a detriment. The pandemic itself is recast as 'not that bad' or a 'falsification', further removing the contemplation of the immediacy of death. And with the immediate obstacle removed the subject is able to slip back into fantasies of eternity, of one kind or another, whether implicit or explicit.

Considering how most Western societies (and many others) view suicide, it seems unlikely to me that it would be considered socially acceptable for someone to choose to live half as long as they had the technical option to. Taking the average age of death as 72, would the mental health of someone who chose to die at 36 from a preventable illness not be taken into question? As with sterilization, and other medical procedures such as birth control more broadly and assisted suicide for those suffering extreme medical conditions, bodily autonomy that runs against greater social expectation is resisted.

Or, if the technology had to be administered early, would those who withhold such treatment from their children be considered guilty of child abuse? Again, in current terms, if a child suffered from a medical condition that would kill them at 36, but which was treatable, would it seem likely that the parents, in our present society, would be charged with child abuse?

It's simply a matter of sliding the mark. Cultural attitudes could (and probably would) remain the same. Our fundamental fantasies already provide the basis for and are predicated on eternities. So the reality of longevity merely slots into extant dispositions. So it may not be as revolutionary as suspected.

There would, of course, be those who rejected the technology, but most would do so, I would say, because they believe themselves to possess an alternate way into eternity, perhaps religious, or to be abducted by aliens, but the goal would be the same, whether the efficacy is up to snuff or not.

I don't think the analysis is the same for someone who chooses to die at 36. At 72 you already had the possibility of living a "full life". Meaning had children, see them grow and probably have families of their own; have a career, and even probably changed it a couple of times... At 36, all of that is physiologically not possible. At 144, I imagine probably not much have happened in the last 60 years... Unless increasing the probability of losing a loved one over some kind of accident.

To me, that is not very appealing... Living a healthier live at my 60s and 70s, and be able to be rock climbing with my grandsons and daughters definitely is... Most probably that will translate to longer life expectancy, but I don't think that by itself should be the goal.

I have suicidal thoughts before. I prefer not to let my mental health condition determine if I want to die or not.
That's not what happened in practice as health care improved. The retirement age has been increasing together with life expectancy.

The market balances itself so that the cost of living adjusts so that an average person would need to work until retirement age. That's why the cost of living is significantly higher in the bay area.

For better and worse, this capitalistic dynamic is what makes the US so productive as a country.

The retirement age has risen far slower than life expectancy.
> The retirement age has been increasing together with life expectancy.

I'm unsure with what the issue with this is. But this also isn't true. People have been living longer in retirement. This is often a talking point when people talk about social security. There's a growing gap between when people retire and when they die, and this means people need to save more and that there is more being drawn from social security.

But I do see a huge difference here. If you can live a thousand years then what's the issue of working your first 100? Or 500? Or 900? You talk about capitalism but recognize that capitalism is about consumption. If you generate enough money to live on passive income you don't stop consuming and the wheels don't stop turning. No one stops consuming till they die, capitalism or not. The rich still get rich. But I'd rather have 100+ years of retirement than 20, even if nothing else changes.

I invite readers to look into SkQ1, thymalin and Epitalon
It seems that their calculations use metformin. At what age should we start using it for health-span extension? I'm already using it to avoid glucose spikes, even though I'm not even prediabetic, but I'm curious if it's known how powerful is the health-span effect is younger humans.
If glucose spikes are bad for you, why not just exclude all foods with a glycemic index? That’s what I’ve done and find my mental health and energy levels have improved substantially.
I used metformin for a bit, but stopped because it was found to hinder muscle growth. I decided for the time being I’d rather look and feel good and not be a fragile waif in the hopes of living a bit longer.

I came to similar conclusions about calorie restriction. These schemes tend to slow or restrict growth and energy levels, which is a real side effect we should be discussing more.

Rapamycin seems promising though. It appears you can cycle on and off it and get most of the anti-aging benefits, while limiting the effects of blocking protein synthesis.

I used metformin for a bit, but stopped because it was found to hinder muscle growth. I decided for the time being I’d rather look and feel good and not be a fragile waif in the hopes of living a bit longer.

I heard the effect was effectively not much, so you should be OK exercising. Just that your muscle gain will be a little bit less. This is just what I heard from other people though, so take it with a grain of salt.

Even if hinder muscle growth by 50%, I might still take it.

I came to similar conclusions about calorie restriction. These schemes tend to slow or restrict growth and energy levels, which is a real side effect we should be discussing more.

I doubt calorie restriction actually works for us. I find intermittent fasting easy.

Personally I believe that the fundamental driver of aging is dna damage. The direct issue is cancer, but the indirect consequence is that the body slows down cellular reproduction to counteract said cancer. This means slower healing of any injuries, and lower vigor.

Thus I see any aging treatment that doesn't fix dna damage as fundamentally a blind alley. And conversely if someone manages to fix dna damage, then the rest should just be some small details.

This article seems to be about the economic value gained by reduced health care or something.

If you actually extended lifespans by a significant margin (say to 200 years) there would be other knock on effects that would completely derail the global economy & markets. This study doesn't seem to think about how those things could actually negatively impact economics.

Eventually if you're intelligent and you're trying to self-fund your retirement you build up assets that are growing at a sufficient rate that you can live off the growth without touching your principal. Once you hit that, work becomes unnecessary.

If everyone goes from retiring for 20-30 years to suddenly possibly retiring for 120-140 years things get all kinds of strange things happening, the percentage of the population working would diminish. But then that would negatively impact companies due to increasing difficulty in finding workers, which would negatively impact markets, which would then feedback into ruining the investments allowing all these retirees to live off investments & savings. The current system couldn't work without room to greatly expand the population of living people to ensure growth of the workforce.

I have seen these ideas explored in Science Fiction occasionally, but not many other places.

There is another aspect as well, if you lived 200 years, what if you ended up having multiple successive families? Raise a family, your kids grow up, then you raise another family 50 years later?

> If you actually extended lifespans by a significant margin (say to 200 years) there would be other knock on effects that would completely derail the global economy & markets

Re-structure? Sure. De-rail? No. One could imagine our current low-interest rate environment (interest rates and time horizons are fundamentally linked) as a first step towards that world.

You're highlighting a problem of retirement savings running out and the labor pool diminishing. These problems offer an obvious solution.

Retirees running out of money because the economy is crashing doesn't really match up with "they'll just go back to work".

People might stop having kids too, then there will be no new workers entering the work force eventually if lifespan was extended indefinitely.

Just increasing lifespans alone would have lots of effects, but they wouldn't be happening in a vacuum. Once we have that type of technology, there's going to be other variables at play.

For instance, I think we'll see close to 100% technological unemployment before we can extend human lifespans by 200 years. In that type of environment, most humans would be effectively retired.

Even if we have less than 100% technological unemployment, birth rates are generally declining, so there's lots of ways that could interact with increased longevity.

EDIT: fixed mispelling

These concerns seem pretty hypothetical because AI's going to be putting everyone out of a job before such things could be an issue anyway.

That said, even in a hypothetical primarily-human labor-market, market-dynamics would fix the problem anyway.

For example: say food becomes scarce because no one's farming. Then the remaining farmers would become rich (they could raise their prices tons) while everyone else would end losing their money to buy the food. Eventually folks would start going into farming until the imbalance is corrected. And, yes, this would mean that those who'd refuse to go into farming would end up draining their retirement funds away -- a retirement fund wouldn't be a permanent no-work ticket, at least in an economy where labor was in too short of supply.

At least, in an ideal free-market economy. In practice, we tend to simplify things and have regulations for practical reasons. Such deviations from an ideal free-market economy might mess up the correction-process.. at first. However, if such regulations did prove to be problematic and prevented the economy from working, then we could just change the laws/regulations to fix that problem -- the simple approach would be to simply repeal problematic regulations.

In short, the stuff you're worried about can't happen (because AI will take the jobs anyway) and wouldn't be a problem even if it could (because market-dynamics fixes such things).

---

Separately, might be worth noting that the big future problem would likely be population-control. Once we have good AI/robotics providing exploding wealth, and then clinical-immortality, it'd be all too easy for people to just keep having endless babies. Doubly so when we have good enough 3-D printing to literally print people, and easy test-tube babies before that. That may be an issue society'll need to address.

mothers used to have kids at age 15 and only lived to their 40s - now folks have kids in their late 20s and live to their 80s
Okay, but what do we do when there is 30 or 40 billion of us?
Population control. Episode 3, Season 2, "Love, Death & Robots" covers a very similar scenario with Black Mirror-like horror...

Effectively, having "unapproved" children results in the children being executed, the parents gaoled for criminal/mental health issues.

Glad they draw attention to the difference between “healthy years” and “just more years”. From our work at GoGo (GoGoGrandparent.com) our clients specifically value more time in the community they grew old in. As you age the trip to church every Sunday becomes what you live for, and taking that away so you can live more years in a retrofitted apartment building isn’t worth it to a lot of people.
I don't expect any noticeable progress as long as medical regulations assume that people already live forever. Avoidance of risk is an absolute priority, even though under current technology level everybody is certain to die. Collective insanity helped by entrenched interest of big pharma corporations.

The only way this changes is if against all odds diy biohacking scene arrives and outright breaks the law by doing human experiments. I got interested a few years ago and concluded until dna synthesis becomes cheap and more reliable for longer sequences it's a pipe dream. That would require a fundamentally new technology (enzymatic dna synthesis?) as current tech is just marginally improved 1970s tech.

Thereputic Plasma Exchange (ie. exchanging blood plasma with saline and albumin) seems a very promising treatment for aging. [1] [2]

"These findings are exciting not only because they represent a scientific advance in understanding aging, but also because they herald the first real anti-aging product that could come to market. Therapeutic plasma exchange is FDA-approved (not for aging, but for a bunch of other conditions). I imagine there remain prohibitions on advertising that it can add years to your life, but it is safe, and a doctor can prescribe it off label. It’s also cheap. An automated plasmapheresis machine—which lets you do treatment after treatment—can be bought online for under $3,000. That is less than the cost of a single transfusion of young blood sold by the startup Ambrosia. How long until someone opens a clinic offering plasma dilution? I bet someone tries it in 2021. If it works, people will get over the weirdness, and it could be commonplace by 2030." [3]
