It's very likely that aging is driven by some kind of scheduled gene program. It makes perfect sense to phase out individuals from a group-level selection point of view.
Is there convincing evidence for group-level selection in evolution at all? I read enough Dawkins back in the day to be skeptical of such claims.

This would be an optimistic scenario and introduce a possibility for the "scheduled gene program" to be controlled or turned off. The current thinking in the field seems to favour the idea that aging is a complex combination of programmed changes, stochastic damage, as well as various adaptations to help cope with the damage.

Life expectancy much longer than 40 is a modern thing for humans though. So where would the over 40s schedule have come from? Or do you mean the schedule basically says: once you hit 50 start falling apart?

Maybe. But why in this case do we not see bugs and failures in this program, i.e. no one lived 5 times more than the average or did not live forever at all, for example? I'm not making a statement, just a guess.
Earlier quoted context omitted.
I started weight training at about age 54. I had never done any form of regular exercise in my life. Attempts here and there, but nothing ever stuck for very long. I am stronger now than I ever have been.
I weight trained until having a toddler and a new house at 50. 3 months later and I get up from a chair like I'm 75 and all my joints hurt.
Your toddler needs healthy parents.
I felt incredibly old from ~36 - 42. Then I started seriously working out, took control of my diet (it had very much always controlled me) and started aggressively pursuing a "better living through chemistry" approach to life. I feel 25 years younger now. My BP and cholesterol are under control and I roll out of bed actually feeling rested (probably due to not snoring anymore).

I’ve been athletic most of my life. At 42 I feel much older than at 32. Chronic injuries add up! Be careful out there everybody
Having lived in San Diego most of my life, I've routinely met people in their 60s doing Ironmans. When you're around that enough, it's clear the difference is training smart than simply training hard.

I feel great when I eat clean.
I've only opened these comments in the hope somebody here will debunk these findings or at least point out they are dubious... :(
