That's an intersting take. I know from my own standpoint, we never talked about concussions in sports. We just called it getting your bell rung. I remember the trainer popping amonia packets to revive guys and having a ringing in my ears after a good hit. I'm approaching 50 now and sometimes feel as if I'm a little more foggy than I should be. Other times, sharp as always. The more I read and learn, the less I like.
The study that bothered me most was the one published in the last year. They performed baseline studies on HS football players before they started the season and all of the kids brain functions lowered as the season progressed. That being said, the brain recovers and the kids functions returned to baseline shortly after the season ended. Scary stuff though, as I have a nine year old that really loves to play.
