At 48, Herschel Walker is not slowing down any time soon.
Instead, the physically-fit former football great has his immediate future mapped out. He plans to compete in one more MMA fight in the fall. He's also mulling a possible return to the NFL in two years.
"Maybe when I'm 50 I'll make a comeback and be the George Foreman of football," said Walker, who retired from the NFL after the 1997 season.
"Right now, I will guarantee you that probably 90 percent of the guys in the NFL I can outrun. I don't think I can play every snap. But today most running backs don't play every snap. But I know I can get on a team and help a team out."
Walker spoke to more than 300 soldiers Thursday at Fort Gordon's Alexander Hall about his life with dissociative identity disorder, a condition he detailed in his 2008 book, Breaking Free . His message to them was clear.
"I'd love for them not to feel that just because you admit you have a problem you're weak, because you're not weak," he said.
"If you've got a problem, go get help."
Walker said he writes all the times as therapy. He penned 1,500 pages (the book was cut to 256 pages) about living with his condition, one which led to him playing Russian Roulette -- the "ultimate game," he called it -- on more than one occasion.
"I didn't hesitate to come out about it," he said. "There's no shame in who I am or what I do, because I know we all fall short of the glory of God.
"We all suffer from something, The man that is really suffering is the guy that doesn't want to go out and get his problem taken care of."
Walker, the former Georgia running back who won the 1982 Heisman Trophy and played pro football for 15 seasons, defeated 26-year-old Greg Nagy in his MMA debut in January. The fight was called in the third round.
Now, Walker's trying to find an opponent and a location for his final MMA fight. Walker said he'll likely compete in Atlanta or Texas.
"People don't understand why I like to do this," he said. "I just love the competition. It has nothing to do with the fighting."
Walker, who founded Renaissance Man, the largest minority-owned chicken company in the U.S., stays in shape with an almost unheard of workout regimen.
When he turns 50, Walker said he expects to hear from NFL teams.
"I don't do too much as a joke," he said. "I'm just trying to use up all the gas while I got it."
