Do coffee drinkers live longer?

An interesting study published in The New England Journal of Medicine finds that coffee drinking among the study’s participants was associated with lower risks of mortality. The study does, however, not reveal whether the suggested relationship is a casual one or simply a correlation. If coffee drinking would have an inverse impact on mortality, it is possible that it affects the brain in a positive way. But it is also plausible that healthy persons for some reason have higher coffee-intakes. Or that coffee drinking correlates with exercising, thus having an indirect effect on mortality.
