Olympic gold medal diver Greg Louganis has overcome a rough childhood, an abusive relationship, addictions to pills and alcohol and an HIV diagnosis in 1988. Now the 50-year-old wants to tackle the challenge of DWTS. "I want to be on Dancing with the Stars," Greg tells People. "It would be such a blast." Hey, he's the same age as Jennifer Grey and has an even more emotional backstory, so maybe it would work for him.
