On this edition of ST Medical Monday, a conversation with Dr. Nadine Burke Harris, the founder and CEO of the Center for Youth Wellness, which is located in San Francisco's Bayview Hunters Point neighborhood. A well-regarded expert on how childhood stress can lead to adult disease, Dr. Harris speaks with us about her new book, "The Deepest Well." We also learn about how and why Dr. Harris -- a pediatrician by training -- was the subject of a game-changing 2011 profile in The New Yorker Magazine. (Please note that you can also access the TED Talk that Dr. Harris gave, which has received well over three million views, here.)
