From birth to death, human beings are hardwired to connect to other human beings. Face-to-face contact matters: tight bonds of friendship and love heal us, help children learn, extend our lives, and make us happy. Looser in-person bonds matter too, combining with our close relationships to form a personal "village" around us, one that exerts unique effects.

Marrying the findings of the new field of social neuroscience together with gripping human stories, Susan Pinker explores the impact of face-to-face contact from cradle to grave, from city to Sardinian mountain village, from classroom to workplace, from love to marriage to divorce. Most of us have left the literal village behind and don't want to give up our new technologies to go back there. But, as Pinker writes so compellingly, we need close social bonds and uninterrupted face time with our friends and families in order to thrive—even to survive. Creating our own "village effect" can make us happier. It can also save our lives.
