The London Olympics is just around the corner and of course, and with all of the performances and stories that will happen there, David Epstein from Sports Illustrated is with us today to give us a heads-up as to what he thinks will be the intriguing stories of these Olympics. Mr. Epstein has been with us for previous podcasts (video here, here, here, and here!) and I appreciate his '30,000 foot' view of sports and the interesting stories in sports medicine.
