Selfish pleasures may offer instant gratification, but the feeling won’t last, The Atlantic reports. Scientists studied 39 teens for a year to see what kept them happier for the long run: selfless deeds or selfish acts. They found that adolescents who engaged in meaningful activities, like sharing their money, showed a decline in depressive symptoms, whereas stingy teens who kept their money and risked it to try to make more showed an increase in depressive symptoms. The results, published this week in the Proceedings of the National Academy of Sciences, suggest that good health may depend on participation in values related to family, culture, and morality.
