Harvard study finds relationships key to happiness

An 88-year Harvard study found that the quality of close relationships is the strongest predictor of happiness, longevity, and cognitive health.

Dr Saurabh Sethi shared that the study tracked the same cohort for 88 years and researchers were surprised by the results.

Relationship quality at age 50 correlated with health and resilience at age 80, including slower cognitive decline.

Chronic loneliness is as physically damaging as smoking 15 cigarettes a day, according to the study.

The key to a good life is not money, status, or physical health, but warm and emotionally deep close bonds.
