Yes, and I don't mind you asking. And honestly I have trouble remembering them all, usually have to ask my mother for the list.

First one came from head to head collision in soccer as a second grader. From football a few year later. Head straight to the wood floor in a basketball game. Another couple diagnosed from football. Got jumped in college and got stomped by 6 guys.

I'm missing some. And I've also gone on to learn that the ones diagnosed from football weren't the only ones I got while playing. I had so many other times I wrecked a dude and went back to the huddle and couldn't think straight or hear but thought that was the old, "got your bell ring" not a big deal thing.

I wish I'd never played football, and would never let a kid play.

Lot of accidents and random occurrences caused the ones in other sports. The football ones all came because of plays that are just naturally part of the sport.
