37-year-old German Oksana Chusovitina (born in Uzbekistan) is staggeringly competing in her SIXTH Olympics in ARTISTIC GYMNASTICS - a discipline dominated by 16 and 17 year olds. She was competing for the German team today (they placed 9th just outside the qualification cut-off for the final) but she individually placed 4th on the Vault and will be contesting the final on August 5.
Honorable mention to 15-year-old swimmer Ruta Meilutyte from Lithuania. She was competing in youth events just a year ago, now she's in her first Olympics and she swam the fastest time in the 100m breaststroke heats. She cried in disbelief after her race. In the semifinals at night, she set a European record by swimming an even faster time and qualifies to the final with a 1:05.21.
Special mention to today's Gold medal-winning skeet shooter Kim Rhode who became the first American (5th in the world) to win an individual medal in 5 consecutive Olympics
