**FILE** Heisman Trophy winner Herschel Walker is in the spotlight after he received his engraved award at the Heisman trophy award banquet in this Dec. 9, 1982 file photo at New York's Hilton hotel. Walker suffers from dissociative identity disorder, formerly known as multiple personality disorder. His experiences are chronicled in his book, "Breaking Free," which is released this week. The 46-year-old Walker was a star running back at Georgia and in the pros. He says he had the condition during his playing days but didn't realize it. He doesn't remember winning the Heisman in 1982 or darker events, such as threatening his then-wife. (AP Photo/Mario Suriani, File)
