Golden Sun, Missing Mojos, and Feng Shui

Sun Yang won his third individual gold medal at the FINA World Championships, adding the 1,500 meter title to his wins in the 400 meter and 800 meter. He kept pace with Canadian Ryan Cochrane for most of the race, and then blasted away in the final two lengths. It was well outside his own world record pace, but he never looked troubled. What's more, he could easily have had a fourth gold: his anchor leg in the 4 x 200m freestyle relay, which pulled China up into the bronze medal position, was a full second quicker than anyone else swam in either the individual or relay events.
