Simone Biles, who is considered the most accomplished gymnast of all time, withdrew from the team gymnastics competition at the 2020 Tokyo Olympics due to a mental health concern Tuesday.  

"Whenever you get in a high stress situation you kind of freak out and don't really know how to handle all of those emotions, especially at the Olympic Games," Biles told reporters on Tuesday. "I have to focus on my mental health and not jeopardize my health and wellbeing."
