The football injury to die for

Most high-school football players aren't concerned about concussions, nor would they tell their coach if they got one. However, Alan Schwarz of The New York Times, gives some compelling arguments for why they should be a lot more concerned. According Schwarz's investigative report, teenagers who receive a second blow to the head following a first, even benign, injury can very easily slip into a "metabolic chain of events," winding up in a coma or even dying. At least 50 high school football players have been killed or have sustained serious head injuries on the field since 1997.
