Perhaps better known now for his famous Foreman Grill, 62-year-old George Forman began his professional career in 1969. In 1994 he shocked the world when at age 45 he knocked out 26-year-old boxer Michael Moorer to become the world’s oldest man to be heavyweight boxing champion. He fought his last fight, a loss to American boxer Shannon Briggs, in 1997, but announced in 2004 that he’d be making a comeback to the ring at age 55. However the fight, against an unnamed opponent, never materialized. He is a two-time world heavyweight boxing champion and won a gold medal during the 1968 Olympics as a heavyweight. His career record stands at 76 wins (with 68 knockouts) and five losses.
