what has been your worst injury in life?

I've never broken a bone, save a skull fracture.

When I was younger (I don't even remember the age - 7 or 8 maybe?) I was playing in the woods behind my babysitter's house with one of my friends who lived next door. He was angry about something and was throwing sticks around; to make a long story short, one clipped me in the face across my left eye. The majority of the force hit my eyebrow, and the rebound clipped my cheekbone below my eye. I got a few stitches in my eyebrow, and the scar can still be seen if you part my eyebrow hair around it. A few fractures in my eyebrow and below my eye, but that is it.

There is, of course, the one time I ran my sister over with my bicycle (unintentionally) and was thrown into a thorn bush...
