How old would Dick Fosbury be today?

Richard Douglas Fosbury was an American high jumper, who is considered one of the most influential athletes in the history of track and field. He won a gold medal at the 1968 Summer Olympics, revolutionizing the high jump event with a "back-first" technique now known as the Fosbury flop. His method was to sprint diagonally towards the bar, then curve and leap backward over it, which gave him a much lower center of mass in flight than traditional techniques. Debbie Brill was developing her similar "Brill Bend" around the same time. This approach has seen nearly universal adoption since Fosbury's performance in Mexico. Though he never returned to the Olympics, Fosbury continued to be involved in athletics after retirement and served on the executive board of the World Olympians Association.
