Padding around his Malibu home in bare feet, a deeply tanned Greg Louganis looks relaxed, rested and remarkably healthy. Gazing out over his backyard pool, with its Olympic-ring logo and a platform perfect for practicing reverse somersaults, the four-time gold medalist gestures to his four dogs and says something surprising: "They use it more than I do." Diving, he says, feels "like a totally separate life."
More than 20 years after learning he was HIV positive—a diagnosis widely seen as a death sentence at the time—Louganis, who turned 50 on Jan. 29, is thriving.
