 Singer Bonnie Pointer, born in 1950, and boxer Leon Spinks, born in 1953. He won a gold medal at the 1976 Olympics and became the heavyweight boxing champion when he beat an aged and out-of-shape Muhammad Ali in a 15-round decision in Las Vegas in 1978. Did this just literally say he won because he's old? It's throwing strays, is what that is. Poor Leon Spinks. But still, either way, he was the heavyweight champion of the world, at least briefly.
