Well, stuff like this happens to me alot, but there are a couple times were it was pretty bad....
back in November 2008 I tried to do a tre flip on my skateboard off an 11-stair....I fell on my face and broke my nose and chipped my front teeth.
The other time I was in a fight and I fractured my arm; when I punched a guy, I tried to punch him again with the other arm but he dodged and I hit into a brick wall ( he was standing right in front of it before )...
Yea, painful stuff. I also have a burn scar on my back from the 8th grade when we were making a bonfire xD And I have a snake bite on my left arm, which I like to tell people I barely survived from....yea, no. It was just my cousin's pet gopher snake, which is completely nonvenomous and hardly a foot long. =/ It's fangs hurt alot, though.
