Brain function can start declining 'as early as age 45' (bbc.co.uk)

As someone who just turned 43, this article makes me very sad.

Wait, what was the article about again?

I often wonder about these findings. To what extent are we seeing a neurologically-driven phenomenon vis-a-vis one generated by a host of factors causing relatively common skill atroph? By 45, many people might be working largely on autopilot, causing flexible skills to decline in favor of scripted response.
