TCon, oooof, I'm not sure you really wanted to do that, did you? hehe.
My worst injury to date is 3 cracked ribs as a result of trying to ollie a two set and having the board slip out from underneath you as you land and subsequently bounce back off the wall and underneath you just before you would have made contact with the floor, your ribs crack off the side of the board, heh. I haven't done a lot of skating since then come to think of it [confused] and that was when I was 15.
Other than that, I had a thing when I was younger for cracking my head off things, or seemingly anyway, requiring an overall total of 46 stitches, on 6 different occaisions over a period of 3 years, in between the ages of 7 and 10. I still bear all the little scars from those now, the most noticable one being on my eyebrow, it looks like I've shaved a little line through my eyebrow, heh.
