In 1938 the Harvard Study of Adult Development began. It followed the lives of 268 Harvard students and 456 inner city kids in Boston, and remains the largest, longest study of its kind, gathering data on physical health, mental health, personality, and social connections. The study's findings have served as the basis for an impressive body of work on lifestyle fulfillment and happiness, and my guest on this week’s podcast has co-authored a book highlighting his learnings. Listen and learn: Why loneliness is one of the greatest risk factors for an unhappy and unhealthy life Why social fitness should be given the same priority as physical fitness How war, hardship and adversity can provide a sense of community that leads toward happiness and contentment Why 20 to 40 percent of the population admit to feeling isolated and lonely Creative strategies to build connections at any age  Links Marc’s Site ABOUT OUR GUEST Marc Schulz, PhD, is Associate Director of the Harvard Study of Adult Development.
