Yet we so often choose to be unsocial. We avoid talking to the stranger who sits next to us. We struggle to move beyond small talk with an acquaintance. We are reluctant to express our gratitude to people we appreciate. Every day, we avoid opportunitiesto connect with strangers, neighbors, colleagues, friends, and family. By missing those moments, we miss out on all the benefits of a more social life—one that is happier and healthier for everyone.
