We talk with John Janovy, Jr., author of our February book, Life Lessons from a Parasite. John is one of the world's preeminent experts on parasites, a best-selling author, and an artist. In this fun and wide-ranging conversation, we discuss parasites, of course, but we also talk about what it means to be a decent human being, how to evaluate ideas and words we're exposed to, how the Vietnam War changed John's approach to teaching, and the fundamental importance of curiosity. We learn about John's early roots in the outdoors and his love of painting. John also tells us about the tapeworm in Robert Kennedy, Jr.'s brain. A jam-packed episode, for sure!
