David Epstein on the Sports Gene

David Epstein talks with host Russ Roberts about his book, The Sports Gene. He discusses a number of the ideas including what we have learned about the nature vs. nurture debate, the role of practice in achieving mastery, why a small part of Kenya produces so many champion marathoners, why major league all-stars can't hit a fast-pitch softball, the strange nature of body types in the NBA and why Michael Phelps's body gives him an advantage.
