my parents are over sixty and they're as good as dead. so i give you a high five for doing good things.
there is nothing more pathetic than a 50 or 60 year old that acts as if they were dead.
yea it's possible to change your body.
on stronglifts there is a guy that started squatting/deadlifting at 62 and now he's up to something like 300 or 400 pounds.
it's never too late.
