Current author David Epistein’s March TED talk, based on his New York Times bestselling books, The Sports Genereleased this week by Current in paperback, addresses this question: Are athletes really getting faster, better stronger? When you look at sporting achievements over the last decades, it seems like human have gotten faster, better and stronger in nearly every way. Yet as Epstein points out in this delightfully counter-intuitive talk, it becomes clear that many factors are at play in shattering athletic records, and the development of natural talents is just one of them.
