It's too little too late for my generation and others. I had a bad run as a junior that led to me being coached by my guard as to who to block and where we were, during a home jamboree. I threw up on the sideline and didn't remember anything until three hours later sitting on the bench with a towel on my head. Cussed out the trainers and coaches etc. this started the week before when I took a hit that everybody thought was overheating at the bottom of the pile during practice.
Being a A and B student my grades dropped, had mood swings etc.
It's real to me. Had a few pretty bad motorcycle accidents too before those diagnosed cases.
