Yay! Welcome back!

As for the Beaters: There is evidence that multiple head trauma over time affects you later. NFL players deal with the same thing. I don't think anyone playing in school. I don't think anyone just playing in school would be effected in their old age, but perhaps the processional Beaters who spend every day of most their life taking hits would have to worry about it more. Less so than a boxer I think, who is literally taking punches aaaaal time time. I think it would be more like foot ball players injuries.
