Medicine is capable of saving lives in ways not thought possible a few decades ago.
Dr. Mark Vonnegut knows this first-hand; he's been a pediatrician for more than 40 years.
He takes note of changes both good and not-so-good in his field, but focuses on personal stories of children he has known and treated in his book The Heart of Caring: A Life in Pediatrics.
Like his famous father, Kurt, he has a knack for telling a tale. The doctor pays us a visit to talk about his book and the long career it covers.
