brain damaging sports

Column by Steve Chapman in the Chicago Tribune: I don't think I can watch football anymore

The most debilitating part of the sport appears to be not the rare concussion but the regular, inevitable blows to the head that occur at every level. A study conducted by Stanford researchers on Stanford players found that in a game, the typical offensive lineman endures 62 such hits, each equivalent in force to driving a car into a brick wall at 30 mph.

Ouch. Same thing with boxing, I'm thinking. But I don't know if I'm at the point where I can stop watching football and boxing. Not yet, anyway.
