I used to think centenarians were as rare as unicorns, but boy, was I wrong! On the Japanese island of Okinawa, there are 457 people over the age of 100. This place isn’t just a hotspot for longevity; it’s practically the fountain of youth. From 96-year-old martial artists to 105-year-old snake-hunters, Okinawa is where the old age gracefully, and with a lot of spirit.
