We welcome to our show Dr. Abdul El-Sayed, a physician, epidemiologist, public health expert, and progressive activist. He was appointed health director of Detroit, Michigan, at age 30, and he was formerly a professor at Columbia University's Mailman School of Public Health. Dr. El-Sayed's new book, which he tells us about, is "Healing Politics: A Doctor's Journey into the Heart of Our Political Epidemic." As was noted of this book by Bill McKibben with 350.org: "This is a very important book. Abdul El-Sayed diagnoses the true epidemic of our moment: the scourge of insecurity, as we face a heartless economy and a faltering climate system. And he provides the prescription: a dose of empathy measured out in legislation and political action. It's a manual for real, deep, and utterly necessary change."
