For 75 years, research has been conducted regarding the question "What makes us happy and healthy throughout life? And if you think it's fame and money, you're not alone—and you're wrong! The psychiatrist Robert Waldinger established an unprecedented approach to information about true happiness and satisfaction in life, based on the longest and most in-depth study in human history to the study of adult life, which followed the lives of 724 men, from youth to adulthood. 60% of these men are still alive and continue to participate in the study. In this lecture, Waldinger shares with us the important lessons learned from the study, as well as the practical and ancient wisdom such as the hills, on how to build a long and satisfying life.
