The following article by Gladwell in recent issue of New Yorker compares American football with dogfighting. The most intriguing part of the article is gathering of data measuring g-forces to players' helmets/heads. Data and subsuquent brain studies indicates that it isn't so much how many concussions a player has as a predictor of future brain damage/dementia, but the cumulative hits. In other words, Mama, don't let your son grow up to be an offensive lineman. Is it possible that the health risks of American football will lead to even more players turning to soccer in the future including those athletes that are often discussed as potential difference makers for the US? It certainly isn't something that will change overnight as we American's love our warriors (this is where the dogfighting comparison comes in). http://www.newyorker.com/reporting/2009/10/19/091019fa_fact_gladwell I have gained a greater appreciation for the sanity of rugby and how the rules and playing without helmets protect players from the kind of cumulative and acute injuries experienced in American football.
