The Harvard Study of Adult Development: The Key to a Happy and Healthy Life

The Harvard Study of Adult Development is the longest study of adult life ever conducted, tracking the lives of 724 men for 75 years.
The study includes two groups of men: Harvard College sophomores and boys from Boston's poorest neighborhoods.
The study examines various aspects of the participants' lives, including work, home lives, and health.
Over 60 of the original 724 men are still alive and participating in the study, most of them in their 90s.
The study also includes the children of the original participants, with over 2,000 children being studied.
The main finding of the study is that good relationships are the key to happiness and health.
Social connections and being well connected to family, friends, and community are linked to greater happiness, better physical health, and longer lives.
Loneliness is toxic and can lead to unhappiness, declining health, and shorter lives.
The quality of close relationships is more important than the number of friends or being in a committed relationship.
Living in the midst of conflict is detrimental to health, while living in good, warm relationships is protective.
Satisfaction in relationships at age 50 is a predictor of health and happiness in old age.
Good relationships also protect the brain, with securely attached relationships in old age being linked to sharper memory, while relationships lacking trust lead to earlier memory decline.
