Unlike in the United States, where youth is worshipped and age is shunned, Okinawan elders are revered. Women in particular are the keepers of the spiritual bonds between the present and the past. In Okinawa, age is celebrated with healing rituals. They promote lifelong health through the practice of dance and martial art, which they believe nurtures your chi.
I read that the Okinawan diet staples include green tea (good), seaweed sheets (not so good), tofu, and eggs.
