I have had loads of things happen to me, yet somehow nothing has been broken.
1 time when I was around 4 or 5, we were playing on the merry-go-round thing at the play ground, and some high school kids came and started spinning it really fast, I lost my grip, and 10 minutes later I woke up and my mouth was bleeding, badly. I went to the ER to find out I almost lost my entire upper lip.
Another time, I was 9 or 10, and I flipped my dad's 700 lb. atv and was unconscious for a couple mins, went to ER and nothing was broken, but they gave me an I.V. and some weird crap, and I got loopy.
And one more, I was playing on crouches for no reason and I was jumping down the stairs and landed wrong, then I found out I had chipped a piece of the bone off my toe, that is it, nothing broken, just chipped. They didn't even take it out :C
