I figure I've probably had a half dozen at least. The worst was from playing flag football of all things. Knocked heads with another guy when we were both going for a flag, I was out like a light for a few seconds and dizzy as all hell when I got up. That was back when you just shook out the "cobwebs" and kept playing. Stupid. I remember a few hits from high school ball where I saw some stars or briefly had tunnel vision.
