Social epidemiology never generates straightforward policy prescriptions. Even if we know something makes us live longer, we still have to ask if it is right to promote it. It might be that many features of more traditional societies, including religiosity and tight social relations, are good for health. But it does not follow that we can or should try to turn back the clock. That is a philosophical and political question, not one for epidemiology.
