Longevity plan: 2-days sleep, 2-days play

TOKYO, Sept. 9 (UPI) -- Everybody wants to know the secret of longevity but a 115-year-old Japanese woman has developed an unusual plan: sleep for two days, then play for two days.

Japan's Mainichi Shimbun newspaper said Kamato Hongo of Kagoshima attributes her longevity to a unique lifestyle of sleeping for two consecutive days, followed by two days of activity. She will turn 116 on Sept. 16.

Hongo has been Japan's oldest person for five years, as well as being the oldest person in the world. She lives with her 79-year-old third daughter and an 18-year-old great-granddaughter. Hongo has 146 children, grandchildren, great grandchildren and great-great grandchildren.

Mainichi said Yukichi Chuganji, 114, who lives in Japan's Fukuoka Prefecture, is the oldest man in the world.
