Interesting.

I asked because people have always perceived me as 10yrs younger, which has a lot of advantages.

Even now, in my 50s, people think I’m in my early 40s.

I too was insanely active, all the time. To the point where I have so many injuries from high risk sports a doctor said I’d technically qualify as disabled.

Less active now (I can’t run as I could) so I expect I’ll be putting on weight soon.

I frankly never expected to reach this age, was convinced I’d die young. Still a bit surprised by my own stamina - but having kids ages you a bit, and also keeps you active so it balances out.
