The oldest living Olympic champion has turned 99 years old. Agnes Keleti won 10 Olympic medals as a gymnast at the 1952 Helsinki Games and the 1956 Melbourne Games and is also a Holocaust survivor. She was 31 and 35 years old during her two Olympics and won five gold medals. Keleti's father and uncles were killed in the Nazi's Auschwitz death camp. She trails only American swimmers Mark Spitz and Dara Torres among Jewish athletes in having the most Olympic medals. Keleti lived for decades in Israel teaching gymnastics before returning a few years ago to Budapest. She says the most important thing children should learn is “the joy of life.”
