5yo-I used to haul ass down this road behind my house with a really steep hill. I was going as fast as I could when I noticed a pot hole in front of me. I slammed on the brake (bike only had a rear brake) but still managed to flip over the handle bars when I hit it. I busted my chin open and had to get 8 stitches.

6yo-Went to home depot with my dad and while there he bought me an industrial sized spot light for me. When we got home I leaned over into the trunk to make sure he didn't forget my new toy. I did this right as he was slamming it shut. I got 5 or 6 stitches on the top of my head. My skin has been really flaky around the scar ever since.

8yo-I was on a rusted metal swinging bench, one that is suspended by chains. I tried to see how fast/high I could make it go. It was at the point where the foot rest below was violently impacting the chair above. It's hard to explain without visuals, but I got down low on the foot rest part to try and keep in from hitting the chair. I was thinking I was strong enough to slow it down. My knee went straight up into the edge of the bench. I fell of immediately, I looked down to see me knee split in half and a huge gaping hole. I could see all the way to the bone for a second and then it just started overflowing with blood. Another 12 stitches for that one.

19yo-I was skinny dipping with a couple friends and some girls I went to high school with. It was the middle of the night at a neighborhood pool. I decided it would be a splendid idea to dive off the seat of the lifeguard stand. I've always been a good swimmer/diver. Well I dove into what I thought was the deep end. On the way down I was like "oh crap, my big hairy balls are gonna smack the water" so i cupped them basically doing a sailor dive straight down into shallow water. I don't remember hitting the bottom. I just remember being on the water afterwards dazed and struggling to get to the side. I was drunk so I didn't feel that much pain, I had no idea how bad it was until my friends started freaking out. I looked in the mirror and my forehead was split wide open. I had to get 17 stitches. I still have a nice little lump and a super kewl harry potter scar.
