WASHINGTON - OCTOBER 28: Retired National Football League player Merril Hoge testifies before the House Judiciary Committee about football brain injuries on Capitol Hill October 28, 2009 in Washington, DC. A recent NFL study of retired players suggested that N.F.L. retirees ages 60 to 89 are experiencing moderate to severe dementia at several times the national rate. Merril nearly died in 1994 after suffering a series of concussions. (Photo by Chip Somodevilla/Getty Images)
