What is the key to living a happy and fulfilling life? The answer is actually quite simple, according to the two scholars behind the longest scientific study of happiness every conducted.

Beginning in 1938, the Harvard Study of Adult Development tracked three generations of families to uncover what contributed to their happiness. In their new book, The Good Life: Lessons from the World's Longest Scientific Study of Happiness, Robert Waldinger and Marc Schulz tell the stories behind their participants' lives and provide key insights on the recipe to happiness. 

Marc Schulz, a professor at Bryn Mawr College, joins the podcast to discuss the book and their study.
