"Life is not about age, it's about energy" Tyson tells doubters ahead of fight

Mike Tyson isn't shying away from questions over his age ahead of the 54-year-old's first fight since 2005 on Saturday. Tyson will face former heavyweight champion Roy Jones Jr at STAPLES Center in Los Angeles in a bout that will include a no knockout rule, no judges and no announced winner.

"It's going to be entertaining because I'm a fighter, he's a fighter and we're going to be in there throwing punches," said Tyson when asked about the fight's unusual rules.
