(CNN)Gymnastics superstar Simone Biles left Tokyo on Wednesday with her fame intact, but changed from the person she had been before the games.
Suffering from the twisties -- a mental condition in which gymnasts lose the sense of where their bodies are in midair -- Biles stunned the world by withdrawing from some Olympics events.
"I had no idea where I was in the air," Biles said in an interview on the "Today" show, speaking of her performance in a team event. "You can literally see it in my eyes in the pictures, like I was petrified."
Biles, who won four gold medals and a bronze in the 2016 Olympics, went on to win bronze on the balance beam in Tokyo, a medal that meant "more than all the golds, because I've pushed through so much the last five years and the last week," she said in a "Today" show interview.
