Dr. Rowan Hooper is Managing Editor of New Scientist, and in his recent book Superhuman, he scoured the world, aiming to answer a few key questions: Why can some people achieve greatness when others can’t, no matter how hard they try? What are the secrets of long life and happiness? Just how much potential does our species have? Rowan met ultrarunners, those who have rebounded from near-death, those who have exhibited exceptional bravery, found incredible happiness, and who have minds, voices and abilities that seemingly the rest of us could never match.  I caught up with Rowan to understand what he learned from meeting our world’s superhumans.
