Summary: Join me for one of the most joyful podcasts of the year, as I interview Dr. Rich Castellano, MD, the author of the new book, The Smile Prescription. According to Dr. Castellano, a smile is the key to health and longevity. Big smilers live longer than weak smilers or no smilers according to some studies.
