(1/18/22) There is a lot more to Mark Vonnegut than simply being the son of an iconic author. As a pediatrician, Dr. Vonnegut has spent 40 years treating children for coughs, fevers, ear infections or whatever the job calls for. His new book, The Heart of Caring: A Life in Pediatrics, is a look back at his career but also the myriad ways that the US medical system has changed in that time. Join us for a journey into the heart of caring in this installment of Leonard Lopate at Large on WBAI.
