Dr. Marty Makary joins us this morning. Pre-order his new book “Blind Spots” due out in two weeks. With kids going back to school today, should cellphones be allowed in the classroom? Dr. Makary gives his reasoning as to why they should not. Dawn pushes back as she thinks this is an overreach. How does the social media aspect factor into being on phones during class time? When does medicine get it wrong? A lot of times, they get it wrong with our food. What inspired Dr. Makary to write this book?
