In Bama County, Guangxi, China, living past the age of a hundred isn’t just commonplace, it’s become a tourist attraction. People from big cities flock to villages like Longhong to meet the centenarians and try to learn the secret of their longevity.
A self-proclaimed 118-year-old has adopted a flexitarian (or semi-vegetarian) diet. “He doesn’t eat much meat,” says his 87-year-old son.
One Chinese researcher suggests that several geological factors there contribute to longevity, including a karst landform, a higher than normal magnetic field, and a nearby fault zone.
