Noah talks with Stanley R. Mohler, M.D., who teaches aerospace medicine at the Wright State University School of Medicine, about the increasing number of people with blood clots and what causes them. Long flights are being linked to a number of patients who have been diagnosed with blood clots. Dr. Mohler says that when we sit in cramped quarters for long periods of time, our blood circulation slows down, causing clots to form. He suggests trying to keep moving about to keep the blood flowing.
