There are more than 58,000 Japanese who are older than 100, making the country the world’s leader for people who live over 80. All the credit for the longevity is given to a predominantly healthy diet, which includes a lot of fish, rice, vegetables, and small portions. The tiny island of Okinawa is a Blue Zone. People there go on morning walks, take dance lessons and stay active. Locals actually age slower also because, according to a study, people there have a higher level of sex hormones.
