How far can we push the limits of the human body? At the Enhanced Games in Las Vegas, a few dozen athletes tried to find out, and The Verge’s Victoria Song was there to watch. She tells us the story of the swimmers, weightlifters, and other athletes who competed, the intense training and drug regimens they underwent, and the complicated mix of pseudo-science and actual science behind the event. Then, she tells us where this project goes from here — because the Enhanced Games experiment is just beginning.
