Your joints ache because you

Your joints ache because you stopped. Your body is incredible, it can do great things. Of course squatting 500lbs at your age is not intelligent, but exercising smartly is.

I blew out my back on a leg press machine in my late 30's. Still to this day it bothers me but only when I stop exercising. To be honest, I don't think I'll ever be able to quit exercising. If I do I'll be in very rough shape.

If Al Bundy (Ed O'Neill) can start BJJ in his 50's, and get a blackbelt in his 60's, then I believe age truly is just a number.
