BANGKOK -- Thailand's Health Ministry says anyone wanting to live past 100 should brush their teeth and bathe twice a day, keep their homes tidy and clothes clean.

In its "simple secrets to longevity," the ministry also advises three proper meals a day, 30 minutes exercise three times a week, six to eight glasses of water a day and six to eight hours rest.It also prescribes a health check-up once a year, avoidance of narcotics, a moral lifestyle, a low-fat diet and maintenance of close ties with family and friends.

Local media reports quoted Deputy Health Minister Decha Sukrarom as saying the recommendations were based on a 1996 study of 156 Thais over 100 -- 120 women and 36 men.
