I broke my back and tailbone while racing someone down some old stone church stairs two years ago, and went sledding a few years back, only to go off the course and slam into a tree hard enough to take all the skin and stuff off my kneecap. Despite the fact that I could see the bone, I just bandaged it after disinfecting it and left it there. There's a scar, but I didn't have to go to the hospital. Right, then there's the time I broke a toe, and didn't actually notice/feel it for three or so days.
