Where in the world do people live the longest?

The Japanese have the longest lifespan in the world. Japanese men live to be 78 years old on average while Japanese women live to be about 85. Okinawa, Japan, has a population of one million and of those 900 are centenarians, or people who are at least 100 years old. Scientists believe this is because the Okinawans eat more soy products than any other population in the world, as well as a wide range of different vegetables and fruit all rich in antioxidants. After Okinawa, the Sardinian mountain town of Ovodda has the most centenarians, on average 5 out of its small population of 1,700. For hundreds of years families in Ovodda have lived in isolation from the rest of the world, marrying into each others’ families, which may result in few genetic diseases.
