Is it possible that having lunch with your friends is just as important in keeping you alive as exercising? That’s what University of Chicago professor Linda Waite is arguing. Her first of its kind research into social well-being has provided key insights into how our social lives affect our physical health.

The data from Waite’s studies have changed our understanding of what it means to be healthy. Now, she’s insisting that our health care and medical industries need to incorporate social well-being into their practice when treating patients.
