He certainly thinks so. Dr Eugster attributes his longevity to the fact that - bar a pause in his early 80s - he has never really stopped working, and in his late 80s decided to focus on his fitness.
He worked as a dentist until he was 75, and is now an athlete who trains three days a week, holds the indoor 200m and outdoor 400m sprint world records for men over 95.

M95 sprinter Charles Eugster is subject of a BBC story and video, and he’s as funny as he is fast. (He holds several WRs at 200 and 400.) "Even at 87, I wanted an Adonis body, in order to turn the heads of the sexy, young 70-year-old girls on the beach," he says. "I wanted a six-pack, but my coach said that we must first work on my bottom, which she said was a catastrophe." The story says Charles, a retired dentist, “attributes his longevity to the fact that - bar a pause in his early 80s - he has never really stopped working, and in his late 80s decided to focus on his fitness. He worked as a dentist until he was 75, and is now an athlete who trains three days a week, holds the indoor 200 and outdoor 400 sprint world records for men over 95.” Now 97, he’s entered in the 100, 200 and long jump at Perth worlds, where he’ll have plenty of W70s to impress.
