It's been an unusual week for Usain Bolt. First, the fastest man in history ended what's been an abbreviated, injury-ridden season. Then a Japanese centenarian challenged him to a race.

Miyazaki Hidekichi, 103, issued the challenge after competing in the Japanese Masters Athletics meet in Kyoto, Discovery.com reports. "Let's rumble," or whatever the Japanese equivalent is, Hidekichi said about Bolt after finishing the 100-meter race in Kyoto in 38.35. (Bolt's 100-meter world record is 9.58; a less than 29-second difference probably doesn't mean much to those born in 1910.)

Hidekichi, who didn't start running until he was 91, has the 100+ record in the 100 meters, 29.83. He says he wants to be the first to record a 100-meter time in the 105+ age group. His times could be faster, but he's not the world's fastest starter, owing to not being able to hear the starter's pistol.

One way he hopes to stay in fighting trim until he's 105 is his diet. He says chewing each mouthful 30 times before swallowing "makes my tummy happy and helps my running."

The video below is narrated in French, but Hidekichi's awesomeness is obvious in any language.
