Is It Time to Retire the Football Helmet?: A story in today's Wall Street Journal asks whether the football helmet is the cause of more head injuries than it prevents. "Some people have advocated for years to take the helmet off, take the face mask off," said Fred Mueller of the National Center for Catastrophic Sports Injury Research. "Maybe that's better than brain damage." The protective headgear, introduced in the '40s, has created a sport in which players lead with their head in tackles and other collisions. Head injuries are 25 percent more likely to occur in the NFL than in Australian football, a "similarly rough" game that never adopted helmets and other protective gear.
