Centenarians often make the news. Reaching a hundredth year is a feat that makes most people want to know the secret to living well and long.

Reuters news service carries the story of Chan Chi, a Hong Kong villager who has reached the impressive age of 107, and is surprisingly spry. Chan Chi credits his longevity to a low-fat diet, regular exercise and… abstinence. Chan has been celibate since his wife died almost 80 years ago.

But while he hasn’t been having sex, Chan still enjoys smoking cigarettes.

Go figure.
