Norris, an ardent supporter of Mike Huckabee, told reporters he believes serving as president accelerates the aging process 3-to-1.
"If John takes over the presidency at 72 and he ages 3-to-1, how old will he be in four years? Eighty-four years old - and can he handle that kind of pressure in that job?" Norris said, as Huckabee looked on.
"That's why I didn't pick John to support, because I'm just afraid the vice president will wind up taking over his job within that four-year presidency," added the action star.
Huckabee himself avoided offering his own opinion on whether McCain is fit for the presidency, saying "Only John McCain and his hair dresser know for sure."
Norris, who has been at Huckabee's side for weeks as the former Arkansas governor campaigns for the presidency, is hosting a fundraiser for the Republican White House hopeful at his Texas ranch Sunday.
