Herschel Walker is no stranger to unique risks.
Considered one of the best college football stars of all time during his stint at Georgia, this is an athlete who has shined in the NFL, as an Olympic bobsledder and, of course, an MMA fighter.
So what does the 48-year-old athletic specimen, who has conquered everything he’s ever tried, do to to one-up himself?
Go back and start all over again, apparently.

According to Walker himself, a possible comeback to the NFL is something he’s been giving a lot of thought to.
"I know I can play," Walker said on a Monday conference call. "If I continue to stay in the shape I'm in now, I know I can play when I'm 50. Right now, if you asked if I can play today, there's absolutely no doubt in my mind I can play football today, that I can help out a team today.
"I 100 percent guarantee you I can help a football team out," Walker continued.
Back in February of 2010 when the question was posed to him, the former NFL great told one and all that he could still run the 40-yard rash in 4.38 or 4.39 seconds.

"I haven't been doing my track work, but I think if I get back into my track work and the way I run, I can still run pretty well," he said.
Walker’s potential return would make him the oldest player in the history of the sport to ever play a game. At the moment, George Blanda, who was 48 during the 1975 campaign, rests as the oldest player to ever take a snap.
Only two NFL running backs have played past the age of 40 – Ken Strong and Jim Thorpe.
Not that Walker is intimidated by the stacked odds. The two-time Pro Bowler played for four teams during his 12-year football career, and retired in 1997 eighth in all-purpose yards.
According to the legend, if he did come back, he would want to do it for his hometown Atlanta Falcons.
"I still say I may try out for football again and show people I can do that, because I want to be the George Foreman of football and come back and do it one more time," he said.
For now, though, Walker has other things to worry about. The 1-0 MMA fighter will square off against Scott Carson in San Jose, California on January 29.
