I’m not a big football fan, but NFL Hall of Famer Junior Seau’s suicide is on my mind this weekend. Seau apparently shot himself in the chest, and his family will donate his brain to be studied for signs of chronic traumatic encephalopathy. That disease has affected many retired NFL players, including at least two others who committed suicide in recent years. Chronic traumatic encephalopathy was found in one former Cincinnati Bengals player who died at age 26. One of the league’s most notorious underperforming high draft picks showed signs of frontal lobe brain damage as a middle-aged man.

Last week Hawkeyes fans celebrated another solid year for University of Iowa players in the NFL draft. Meanwhile, Superbowl champion quarterback Kurt Warner says he would prefer that his sons not play football. I feel fortunate that my sons have never showed any interest in that sport. The NFL is trying to punish excessive violence on the field, but I don’t know whether it’s possible to separate chronic head injuries from the way the game is played.

This is an open thread: all topics welcome.
