I broke my nose by falling on my face.

When I was a little kid, like 11, I hit my ring finger on a skateboard and seriously fucked something up, but didn't break it. Had a splint thing on for a few days, and hurt like a bitch and couldn't do anything for a few weeks.

Other than that, never done anything SERIOUS.... Currently limping because a pine needle went through my foot and I have a nice swollen infection in the ball of my left foot now, that doesn't seem to be getting bigger or smaller after a week+.....

Done a few nice things requiring super glue, including stupidly using a double edged dagger of my own creation to try to cut a resin ball.... that I was holding. Exactly as you would expect, it went half way through, slid to the side, and I felt it hit the bone in my left thumb. Had to wake up my passed out drunk room mate for his super glue, bled all over everything. Took a lot of glue to hold shut, and it was right in the middle of the pad, so the glue kept getting flooded with blood, like a bruise behind super glue skin. Took forever to heal, and then I'd used so much glue I had a hard spot for months. But it's finially normal again. (typing this I just realized there's a little sliver I still can't feel properly, where the glue was.....)
