This half of Season 1.5 closes by grounding our philosophy — "cherish the companions who rejoice together" — in the science of health. A famous research synthesis integrating data on hundreds of thousands of people compared predictors of long-term health and longevity and reported that the richness of social connection was among the strongest, with loneliness argued to rival widely known lifestyle risks. The director of a celebrated decades-long study of adult life concluded that what most determines happiness and health is neither wealth nor fame, but good relationships.
