I have never broken a single bone in my body that I'm aware of(Knock on wood!). I did however rip my ACL to shreds while making a snowboard bigjump a tad bigger than it needed to be. I came in on the kicker way to fast and overshot the landing hill for a much more exiting flat landing at the bottom... Best part is I tried to walk it off, I got about five steps Before hearing my knee make a somewhat alarming crackling sound. At that moment I decided it would be a better idea to sit on my board and ride it down.
I also Have had a couple of knocks to the head resulting in some blood and sanityloss, and this may be the reason I took up skydiving...
Also: Yay, my first post on this forum In the words of the late great Douglas Adams: Don't panic!
