For 72 years, researchers at Harvard have been pursuing the complicated answer to a relatively simple question: What makes us happy? In the late 1930s, researchers began to follow 268 men as they entered college. Researchers studied their education, career, marriage, children, and other important life decisions as to how it effected their happiness. The study continues today, as the men are now elders, making it one of the most comprehensive longitudinal studies in history.
Dr. George Vaillant directs the Grant Study, and in the video below explains what he's learned about happiness as his subjects have learned and aged.
