I have had no serious injuries in my life whatsoever. The closest thing to one was when my younger brother decided to stab my back, around the left shoulder, with a dull pencil. He also dug his nails into my wrist that caused tiny cuts. I have had only one papercut in my entire life.
Umm... Oh! When I was an infant, my eyelids/cheeks (I forgot) covered my tearducts, so it would cause any tears to pool up until it spilled out in large quantities.
