This week, Matt is reengineering the business of healthcare with Dr. Robert Lahita. Dr. Bob is the Director of the Institute for Autoimmune & Rheumatic Disease at Saint Joseph Health in Paterson, NJ, and the author of the new book, Immunity Strong: Boost Your Body's Natural Healing Power and Live to 100. In part one, Dr. Bob talks about how he 'stumbled' into a career in rheumatology and immunology and the technological explosion he's seen in medicine.
