Here is a comprehensive summary of the Wikipedia article about Simone Biles:
Simone Biles, born March 14, 1997, is an American artistic gymnast widely regarded as one of the greatest athletes of all time. She is the most decorated gymnast in history, boasting an astounding 11 Olympic medals and 30 World Championship medals, including 23 golds. Biles has also secured a record nine United States national all-around championships, becoming the oldest female gymnast to win the title in 2024.
Despite withdrawing from most events at the 2020 Summer Olympics due to "the twisties"—a temporary loss of air awareness—she made a remarkable comeback, notably leading the U.S. team to gold at the 2024 Olympics and securing individual titles. Her pioneering spirit is evident in originating some of the most difficult skills on women's vault, balance beam, and floor exercise. Recognized for her unparalleled achievements and influence, Biles was awarded the Presidential Medal of Freedom in 2022.
