Interesting read. I'll chip in with some experiences.
-Out camping, a large pan of water on a tiny propane burner to cook inside the tent because of rain, sitting next to it with thick socks on. Wind makes the tent move, throwing over a bottle against the pan, 2l of boiling water over my feet. Very painful.
-Broke my leg falling down something I had climbed on (age six). Not as bad as the time when I was 18, crashed my motorcycle into a truck coming across the road, falling underneath it while it still moved. Broke both the bones in my lower leg. Truck driver hadn't seen me with the sun low, only used his brakes when he heard a loud bang. I almost cleared the truck, but for my head. Luckily the truck stopped when one of the wheels was inches from my head. Worst part was actually in hospital when they tried to set the bones with me on nitrous gas. The procedure is still very painful despite the nitrous gas, and the nitrous makes it a scary experience. After that, they set it in a cast, only to hear the bones snapping back off again. I had to get surgery and metal pins inside.
-Jumped onto a broken beer glass in the pub because I was being an idiot, bottom of the glass didn't break and a very large part of it pierced my shoe and heel. I almost fainted and the shoe was drenched in blood.
-Experimenting with fireworks, having stuff exploding in my hands hurt. One time I had to go to the hospital because one of my finger tips was in pieces.
This was all in my childhood/teen years. Now I try to keep my children out of harms way as much as I can, still many years to go
