In these places in the world you have the best chance to live to a ripe old age

The 2004 study of the population of the southernmost island of Japan showed that there are 400 people over 100 years old in Okinawa. Scientists often questioned their diet in an effort to find out why they live so long. What differs them from the rest of Japan is: in Okinawa, people eat less rice, but many sweet potatoes. They take in 30 percent less sugar than people in other parts of Japan. More recent studies show that Okinawa is no longer the first in the list of the longest life expectancy regions in Japan, but it still belongs to a “blue zone.”
