When I was about...10 or 11 and was skating all the time I decided it would be fun to skate off of my 14 foot roof onto a deck then off another drop only to fail and fall like 20 feet strait on my elbow and shatter it into 6 or so pieces(I don't rember the exact number) anyways I had to get to metal rods called pins INTO MY ARM for a half a year until my bone seals back together and because they did surgery I also had stitches...now I have scars all on my left elbow :)
