Too continue the topic...I got hit by a flying coffee can when I was 8 or 9. I was at a boy scout egg drop activity. The eggs were being dropped from 25 feet, and we were supposed to put them in something to keep them from breaking. Well, somebody put theirs inside a coffee can with a parachute on it. It was windy and...well you get the picture.
I went to the Doc and he said I would not scar from it. I still have about a 2 inch scar on my forehead from it. So, from this story we can make the assertion that Doctors lie.
