Ive never had any serious injuries, never had a broken bone. The only problem I have is in my knee where I have Osgood Schlatters disease (Definition) it was excruciating when i first had it, I used to fall off the school bus and fall down stairs etc . But now its just painful when its cold and if I over exert my knee.

Having read that, it's good to know it actually goes away, although there might be slight pain occasionally for some in adult life.
