Able bodied people only cheat themselves by being lazy IMO
A body is like an engine. It's going to be junk Someday anyways so might as well put as many hard miles on while you can. And I don't mean drugs and stupid crap. I mean staying healthy and feeding it good fuel and workout a lot and rev it up and be as active as possible. When it finally throws a rod and hits the junk pile, no regrets
