Tal Flicker, Israel – A gold medalist at the 2017 European Open, Flicker first got into judo when his father took him to a martial arts center. "I think the most obvious value people can take from judo and apply to their lives is respect," the former world No. 1 told CNN during the 2018 Paris Grand Slam. "Before a fight, you give a bow to your opponent. Then you fight like you want to eat each other, but at the end of the fight you shake hands and bow again. Other sports could learn from that."
