An interesting article in the Economist which discusses a positive link between virtue and health.
THE Greek founders of philosophy constantly debated how best to live the good life. Some contended that personal pleasure is the key. Others pointed out that serving society and finding purpose is vital. Socrates was in the latter camp, fiercely arguing that an unvirtuous person could not be happy, and that a virtuous person could not fail to be happy. These days, psychologists tend to regard that point as moot, since self-serving “hedonic” pleasures generate the same sorts of good feelings as those generated by serving some greater “eudaimonic” purpose. However, a study just published in the Proceedings of the National Academy of Sciences, by Barbara Fredrickson, a psychologist at the University of North Carolina, Chapel Hill, and her colleagues suggests Socrates had a point. Though both hedonic and eudaimonic behaviour bring pleasure, the eudaimonic sort also brings health.
