People in the world live on the average of 72. In three areas of the world, Ecuador, Italy and Japan, a very high number of people live to be 100. Scientists want to know why. In Ecuador, there is a small village, Vilcabamba. People call it "the Valley of Long Life." The weather here is not very hot or very cold and the air is very clean. People work hard and exercise a lot. They have a healthy diet. They eat a lot of fruit and vegetables and they don't eat meat or fish very often. The water they drink is from the river which is rich in minerals. They also have good social life. People here always say: "The left leg and the right leg help you to be healthy, because they take you to your friends' homes."
