Yet the Harvard Study of Adult Relationship, one of the longest and most complete studies of adult life ever conducted, found that good relationships, not wealth or fame, keep us happier and healthier.
The study followed two cohorts of white men for 75 years, starting in 1938:
- 268 Harvard sophomores
- 456 12-to-16-year-old boys who grew up in inner-city Boston.
The researchers came away with one key finding: Good relationships keep us happier and healthier. No surprise, people who said they were lonely reported feeling less happy, and exhibited poorer physical and mental health.
