The National Football League players union has chosen Harvard University to lead an unprecedented effort to understand the long-term health effects of professional football. Among the risks involved in the sport, repeated blows to the head have been linked to violent behavior, depression and the deaths of several players, including Junior Seau, a former linebacker for the New England Patriots, who committed suicide last spring.
There's a lot at stake for the National Football League, which faces more than a hundred lawsuits from former players who allege the league did too little to warn or protect them from the hazards of the sport. The goal of the study is to improve the health of active and retired players within five years.
