There is a happy medium between taking a risk or two and subjecting your brain to consistent abuse. I can climb mountains in such a way as to minimize my chances of falling hundreds of feet, but there is no way to play football without your head getting smashed around.
So what you are suggesting is that high school football be banned.
Is that your point?
But...but...in high school we were all indoctrinated that football players & star cheerleaders possessed those superior genes with which to continue the best of the human race, and the rest of us were nothing but insignificant nerds.
Is...nothing...sacred?
