There are quite a lot of factors that affect lifespan. From what I understand from reading those studies, factors such as lack of stress, strong social contacts, exercise, sunlight exposure and good diet all likely play a large part in reducing mortality in these populations. Perhaps they would live even longer if they drank alcohol free wine? And how much wine do they actually drink?
