We've profiled some people who manage to stay young at heart, but they've got nothing on corporal Richard Overton, who hardly looks his age after turning 111 a few months ago. For more than 70 years, he's been a fixture of his neighborhood in Austin Texas, where he spends his days sitting on the porch of the home he built himself.
He's easy to find, because the city has renamed his street Richard Overton Avenue, and he'll probably greet you with a smile and a wave as you're walking by.
But what keeps the friendly "supercentanarian" - and the world's oldest living World War 2 veteran - fit in his old age? Thankfully it's not daily exercise.
Overton says 2 things have kept him alive for so long: enjoying his cigars (he smokes about 12 a day) and his faith in God. It may sound like a stretch, but the results speak for themselves.
Born in 1906, Overton is older than paper towels, and the same age as radio broadcasting. He was married twice and outlived all his family except a few cousins.
He's seen his fair share of history too: Overton arrived at Pearl Harbor just moments after the Japanese bombing, and spent World War 2 serving in the Pacific, including a stop at Iwo Jima. He even got the chance to meet President Barack Obama twice at Veteran's Day ceremonies.
Unfortunately, Overton's health has been declining in recent years.
