1. Mild - Serious concussion from kicking a soccer ball against the garage door. All I remember is kicking the ball then waking up a day later in the hospital with a really bad hankering for barbeque potato chips. I ate part of a bag in the hospital, then got sick. I cannot stand the smell of those chips anymore, every since that incident I get sick even thinking of the smell of them
2. Broke a broke a bone in my wrist punching a door when I got angry over a game of risk. Ended up getting 2 pins and a bone graft to put the two ends back together. I lost about 10-15% mobility in my right hand, and it hurts me every day. Needless to say I learned my lesson at the ripe age of 19.

Kinda makes me angry enough at myself I want to hit something, LOL.
