Why do engineers shake their legs behind a desk??

It is just me or is it that when engineers are programming and sitting behind a desk, they constantly shake their legs??

I don't.
(comment deleted)
Nope, I don't do that.

I have a neighboring coworker who does, though, which can get annoying as it ends up making my monitor shake too.

Don't do that. But I switch about once an hour between sitting down and stand up desk.
I do, but I'm not an engineer. My brother does too and he actually is an engineer, though. I guess it depends.

I've noticed I'm more prone to nervously shake my legs (usually one at a time) when I'm being overly creative.

I do - and most of my team do the same :) Funny that you mention it..
My girlfriend does this and she's not programming or engineering-minded.

It's just a habit that people seem to have adopted lately – we see other people do it and pick it up because it's comforting.

It isn't just engineers... Everyone does this. It's just a habit that people have like pen clicking or nail biting.
I do it. I think it sort of gives me a sense of comfort. But it seems to run in the family - on my father's side. My dad shakes his leg. As do my brother and yours truly. My paternal grandfather is a leg-shaking champion. I can't say for sure, as he is dead, but I'm pretty sure my paternal grandfather's father would out-leg-shake us all combined.

And then, on my mother's side, nobody I can think of does it. My mother hates leg-shaking. I try to be decent about it when she's in the room. Fortunately, my wife - who doesn't approve of legshaking, and seldom shakes a leg - doesn't really give me grief about it. Guess she's written me off as a leg-shaker, and accepted it as one of "those" things.

someone's quitting smoking i see
I never smoked and still doing that sometimes. Think it's just a habit and it has nothing to do with engeneers. My dad does it too, but isn't an engeneer.
Funny - I haven't smoked in months and I've noticed myself doing more leg shaking now.
I do it mostly when I'm slightly stressed: close to the deadline or something like that. It's very unconscious.
It's a habit some people have. When I'm really trying to get a lot of programming down I am trying to shut out distractions so I can focus on what I'm doing. For me this means having everything just so, my monitors a certain way, programs laid on it a certain way, headphones on, music loud, some sort of snack and drink right next to me. Anything that seems off bothers me and I'm sure I do some weird things physically while I'm programming, likely move around to the music I'm listening to, but I don't really think about it. Thats just what I do when I'm trying to shut everything out. People who shake their leg likely aren't thinking about it, it just happens.
Engineers usually drink a lot of coffee / tea, thus are hyperactive lots of the time. A lot of them are nervous, have a tick, find it relaxing. Sitting in the same position for hours on end also does not help.
nothing to do with being an engineer. My dad does it and he is not an engineer. I guess it is just a habit.
Geez... why would this have anything to do with "engineers"?

Engineers are not some special creature.

Whaat? I had a stint in college studying Mechanical Engineering. You have to basically chain yourself to a desk and become an actual recluse-hermit mutant creature if you want to get through. I'd say that's pretty 'special' - in a certain context.
Perhaps a better wording would be: why do you consider leg shaking to be exclusively the realm of Engineers?
I think it's a combination of factors, one of which might be that the lymphatic system requires motion to cause it to flow (it has no "pump"). So "fidgeting" feels good.
No real answer to add, but when I was younger I used to play chess pretty regularly.

At every tournament there would be people shaking their legs like crazy under their tables.

I think leg shaking is mostly harmless, the habits I worry about are:

1) Constant muttering stream of expletives.

2) Unconsciously drumming along on my desk to whichever song I happen to be listening to while waiting for code to compile / servers to start / etc.

I don't think I actually do either very often, but I worry about it. ;)

If you are not doing "1" then you are doing it wrong :-)
I find that the first option mixed with an extreme amount of self deprecation is like taking a riding crop to the part of my brain that works really well. Unlike the rest which is a procrastitative mess.
I am surprised people comment on this "question" including me. Engineers are strange people.
Uh, engineers are just people. They aren't any different from other people in the wild.
That was sarcasm. I know we are just regular people. But the question implies we are aliens.
ah. sorry.
Are you available for hire this weekend?
Amazing how you can almost always find a relevant xkcd: http://xkcd.com/228/

(also, why is this on the front page?)

Brilliant! How do you guys always manage to find the relevant ones? There's hundreds of them, and I tried a few google searches using site:xkcd.com and some related terms and couldn't pull up this one.
It's an art. You are either born with or have to learn it "the hard way". ;-)
Kinda like spitting (with high initial thrust and decent precision). Or doing a double-snap thingy with your thumb or other extremity.

I was born capable of all three. I still wonder if I'm destined for Great things, or just a freak

Either way you must have made a name for yourself in your circle and more. I envy you for the 'snapping' prowess. However, as far as spitting goes I might qualify to be a master spiter(please read as in sniper).

By the way, just high initial thrust and precision are not enough you have to got to use the ammo in the right amount w.r.t. distance and all. Not to mention you have to mind wind conditions, otherwise the drop might land at someone standing/sitting/moving near by.

" Not to mention you have to mind wind conditions..." I can calculate the vector angle, wind considered, to almost 0.99% accuracy. Zero dot nine nine, my friend. While driving on the freeway.

"...otherwise the drop might land at someone standing/sitting/moving near by." But then there's no reason to spit in the first place, is there?

The XKCD-Oatmeal theorem. For every wonder-why that is spawned in the universe there exists an appropriate XKCD and/or Oatmeal.
>It is just me or is it that when engineers are programming and sitting behind a desk, they constantly shake their legs??

It's just you. I've worked in several teams and maybe one in five does that. So no "engineers" as in "the majority of them".

Occasionally of course (once an hour or a couple of hours), all do it and SHOULD do it. For the same reasons you are told to do it in an airplane. Thrombosis et all.

Can someone pie chart this?
IAMA under-desk leg jiggler, AMA. (P.S. I also chew pens.)
Yuck!

Or maybe okay. I chewed few when I was in school. Was spanked without mercy and the spanking got rid me of the habit. Can't complain.

Q: Any favourite colours or flavours? Fountain or ball pen?

Any pen that's going, really, other than if they're metal (impossible to chew) or seemingly poisonous (e.g. dry markers). No real preference, although I tend to regret chewing biros as they shatter into pieces easily.
Venous and/or lymphatic systems use muscular contraction and movement for fluidity. It is specially important to counter gravity. The "need to move your lower extremities" is a natural instinct.

So it's not "an engineers thing". I'd say it's not even a "humans thing". Try "animals" (with lower extremities and veins and/or lymphs).

Disclaimer: I'm not a doctor or a vet.

For me it's not only shaking legs behind a desk. It's also walking in circles when talking on the phone. It's also doing something with my hands when I'm not at the computer (preferably with some item like pen or phone or anything what's nearby).

I consider it as a soft version of light ADHD, but I doubt it has anything to do with my profession. It might be the other way around - I chose a profession where I create new things because of that trait (which might also be connected to me being easily exited about new things).
