101-year-old Buster Martin is training to become the world's oldest marathon runner when he runs in the London marathon next month. He ran the half marathon last weekend, completing it in just over five hours. It would have been faster, he says, but he says he stopped for a beer and a cigarette ;-)

"He smokes, drinks, stays out late, which is probably why he is still alive," said Charlie Mullins, the managing director of the plumbing company where Martin cleans vans. When not working three days a week for Mullins, Martin can be found in a nearby boxing gym working with a pair of trainers in preparation for April's run. He refuses to be impressed by the fact that he is still running. "I am not doing anything unusual. I am just running a marathon," he told ABC News. Age is no more an obstacle to Martin's running than that strip of winners tape at the finish line. "You are never too old to do what you enjoy." And Martin likes running, "but not as much as I like my beer," he added.

17 kids, avid beer drinker, smoker and runner....this guy should be the Man of the Year! Anyway, I bet his power comes from the beard! :P
