Ali was diagnosed with pugilistic Parkinson's syndrome in 1982, following which his motor functions began a slow decline.Despite this, he remains a hero to millions around the world. In 1985, he was called upon to negotiate for the release of kidnapped Americans in Lebanon. In 1996, he had the honor of lighting the Olympic flame in Atlanta, Georgia. At the same Olympics, Ali was also presented with a replacement gold medal. He had supposedly thrown the previous one, won in 1960, into the Ohio River after being refused entry to a restaurant, confirming his own suspicions that even with a gold medal, he would not be treated any different in the South. His daughter Laila Ali also became a boxer in 1999, despite her father's earlier comments against female boxing in 1978: "Women are not made to be hit in the breast, and face like that... the body's not made to be punched right here [patting his chest]. Get hit in the breast... hard... and all that."

The $60 million Muhammad Ali Center is scheduled to open in downtown Louisville, Kentucky in the fall of 2005. In addition to displaying his boxing memorabilia, the center will focus on core themes of peace, social responsibility, respect, and personal growth.
