Japanese live longer!!

In National Geographic(June1993) by an anonymous narrator, the author discusses the issue of Okinawa: A Terrific Place to Grow Old. She states that Japanese live longer than any other nationalities. She supports this statement by giving a percentage that compares Japan and USA. The author also explains that people from Okinawa have some control about their life-style, diet and attitude. In addition, to clarify this point, she describes that the Okinawans eat a low-salt, low-fat food, local fish, lots of tofu and seaweed. One example is one Japan's oldest man, who is 108 years old named Genkan Tanaki now stopped drinking beer and drink hot water instead. Finally, the author draws the conclusion that Okinawa people are active and creative, those are the reasons why they live longer.
