Longevity

TOKYO (Reuters) - The world's oldest man celebrated his 113th birthday on Thursday, telling reporters at his home in southern Japan about his joyful life and healthy appetite.

Tanabe, recognized by the Guinness Book of World Records as the oldest living male last year, eats mostly vegetables and believes the key to longevity is not drinking alcohol.

..."He's said he wants to live for another 10 years, that he doesn't want to die." The Japanese are among the world's longest-lived people, with the number of those aged 100 or older at a record 36,276, a government report last week showed.

I have been said that I would live longer by a fortune teller. Why do many Japanese people live longer? I am wondering if these people are happy. That old man says he's happy. In terms of economics, it's an interesting topic what makes people live longer.
