Michael Phelps turned 30 on Tuesday, which means his Olympic debut in 2000 was half a lifetime ago.
Phelps shares his birthday with actress Monica Potter and boxer Mike Tyson, who both have loose Olympic ties.
Potter played 1972 Olympic 5000m runner Steve Prefontaine‘s girlfriend, Mary Marckx, in the 1998 biopic “Without Limits.”
Tyson reportedly first met Evander Holyfield at the 1984 U.S. Olympic Trials, where they competed in separate divisions. Tyson did not make the Olympic Team, while Holyfield won bronze in Los Angeles.

But back to Phelps. He has more Olympic medals (22) and golds (18) than any other Olympian and could become the first U.S. man to swim in five Olympics in Rio de Janeiro. Dara Torres, whom Phelps called “mom” when he swam in 2000 at age 15, is the only other American to swim in five Olympics.
