Good words! Seems like you know more than a little about the subject.

Until ex-football players started dropping, the general public and especially athletes did not seem to understand just how serious concussions are. Every rung bell (football players like that one) represents brain damage. It may not be much but it is damage just the same. All those brain-rattling impacts (boxing, blocking, soccer) add up.

Apparently, too, aged brains are even more easily damaged.
