Michael Phelps wondered if watching others compete at the world championships would pique his desire for another comeback. Nope. Phelps said Tuesday he has “no desire” to return to competitive swimming, but he is eager to stay involved with the sport and cheer on those who follow in his enormous wake. In an interview with The Associated Press while promoting a healthy pet food campaign, Phelps said he is excited about having his second child and building a life beyond swimming. “For me, it’s about being happy where I am and happy where my family is,” Phelps said.
