In Okinawa island, there are more than 457 old people who are already over 100 years old. Here the average age of female is 86 and of male is 78. It's really a long life island.
It's said the old people in the island not only live a long life but also meaningful.
And the secret for the these people to live long life is because of the the healthy food there and life without pressure. It doesn't mean that people there don't work, on the contrary, some of them work till 70 to 80 years old. They live happily, never get angry.
About the healthy food there, they mainly eat fish, rice and vegetables. They also grow vegetables themselves. The local also drink, but they only drink a kind of alcohol named Awamori.
But in recent years, because of the developing the tourism, there are some fast food and hamburger shops there too, and the young like to eat the food like this. In the same time, the rate of long life decreases.
