It would be ill-advised to compare war and a sport, but I don't think the brain knows the difference. With post-traumatic stress and traumatic brain injuries in blasts with veterans, we see a very similar and somewhat unique issue with repetitive brain injuries in football.

About 10 percent of the time, I miss 3 to 5 percent of the game. I look back, and I'm happy that I played. I'm not wistful. You miss big games. I miss the locker room camaraderie. Sometimes I miss the lifestyle.

A piece of my heart will always be in football, but my mind ended it.
