Harvard Study of Adult Development

“The Good Life” by Robert Waldinger and Marc Schulz is a book that explores the secrets of living a happy and fulfilling life, drawing on the insights of the Harvard Study of Adult Development, one of the longest-running studies of adult life ever conducted. The study followed two groups of men, some who were Harvard sophomores in 1938, and some who grew up in Boston’s poorest neighborhoods, over the course of 75 years.
