TED: What makes a good life? Lessons from the longest study on happiness | Robert Waldinger

The video discusses the Harvard Study of Adult Development, which tracked 724 men over 75 years to understand what keeps people happy and healthy. The study found that good relationships are crucial for happiness and health, more so than wealth or fame. Social connections improve physical and mental health, while loneliness is detrimental.
