I was joined by Dr. David Katz for a conversation about COVID-19. Dr. Katz has been at the forefront of looking at the data when it comes to making decisions about whether to shut down or not.  Take a listen as we talked about the responses to COVID-19, why he believes this virus is unlike anything we've ever seen, and why he's optimistic about the future. David L. Katz, MD, MPH, FACPM, FACP, FACLM is a Preventive Medicine specialist and globally recognized authority on lifestyle medicine. He is the founding director of Yale University’s Yale-Griffin Prevention Research Center (1998-2019); Past President of the American College of Lifestyle Medicine; President and Founder of the non-profit True Health Initiative; and Founder and CEO of Diet ID, Inc.
