The Italian village of Acciaroli, close to Naples, counts an unusually high proportion of centenarians among its residents - 81 from a population of 700.The average life expectancy in the village is 92 years for women and 85 for men.Researchers who looked into why so many of the villagers have such longevity, presented their findings at the weekend."Is there something in their genes, along with something that they do, that makes them live longer and healthier lives?" asked research leader Alan S Maisel of the University of San Diego.He suggested that the villagers' Mediterranean diet was likely to be a contributing factor."They eat rosemary almost every day and they grow it," he said."Maybe this does something that helps. We know that rosemary improves brain function."They are also all physically active. Whether it is fishing, walking or gardening, everyone does something every day."Those weren't the only physical activities that drew the researchers' attention."Sexual activity among the elderly appears to be rampant," Maisel said."Maybe living long has something to do with that. It's probably the good air and the joie de vivre."Maisel also noted that the number of very old people was split evenly between men and women in Acciaroli. Usually a significantly higher number of women live longer than men."It may have something to do with the fact the older men do nothing but sit outside cafés and are less stressed," he said.Researcher Salvatore Di Somma of the University La Sapienza in Rome indicated that the research findings may be useful for anyone hoping to live into old age."What we would like to create is a sort of clinical score sheet," he said, "a tool that says that someone who wants to live well for a long time should have a certain type of diet, a level of physical activity, and a certain way of thinking."..
