You have to do better than that. Give us more information to analyze, instead of just saying something like, "dropped on my head when I was a kid,
anyone know why?".

Seriously. You can't honestly expect people to bite... Maybe if you provided some detail. Besides, you make it sound as if you just now
discovered these scars yesterday. I think I would notice something like that.
If you really have these scars of "unknown origin", post a picture of them.
