Ive never had horrible injuries either...although.
I split my skull open once by slipping in dog urine and face firsting into a hard wooden cornerpost. They glued it back together but a glove piece got stuck so I had a glive inside my head for a week.
I had a canoeing accident where I had no ability to go anywhere and lost contact with my family for a couple minutes. Ended up having to do an uphill backflip to get out.
Used to have seisures I guess...I can still completely roll my eyes.
Think that's about it...I try not to be stupid often.
