This is our second installment of happiness week on the Plain English podcast. On Tuesday, I spoke with the directors of the Harvard Study of Adult Development about what makes a good life, based on their 80-year longitudinal study. Today’s episode is about the phenomenon of rising teenage unhappiness. What's actually happening? Why is it happening? What theories make sense, and what theories don't? How can we fix this problem? Today's guest is Matthew Biel, the chief of child and adolescent psychiatry at Georgetown University Medical Center, and chief medical officer at Fort Health.
