Anyone on Twitter or Facebook knows people like to share, perhaps more so now than ever before. They share what they had for dinner, what song they have stuck in their head, even how wet they got walking into work this morning.

It can all sound a bit like too-much-information. But it turns out there may be a reason for that. According to new research from the Social Cognitive and Affective Neuroscience Lab at Harvard, that kind of sharing may give our brains a neurochemical boost. The research was led by Harvard psychology graduate student Diana Tamir.
