Shannon Miller, the most decorated U.S. gymnast in Olympic history, provided a perspective only another gymnast could give when it came to Simone Biles’ decision to retire from the team final on Tuesday for psychological reasons.

“What I think is really important here is that you have Simone who clearly knew something was wrong, and when you’re flying and tilting and spinning 10-15 feet off the ground looking for a landing, you’d better be doing the right headspace or really bad things are going to happen, “Miller said in an interview on Tuesday night on CNBC’s The News with Shepard Smith.

Biles said she was not in the right shape to continue the competition.

“Physically, I feel fine,” she told Hoda Kotb on the NBC show “TODAY” after she retired. “Emotionally it varies depending on the time and moment. Coming here to the Olympics and being the main protagonist of the Olympics is not an easy task. So we just try to take it one day at a time and we’ll see.”

Miller, who has won a total of seven Olympic medals, told host Shepard Smith that Biles was sending a critical message to the world.

“I think it is so important to have the message sent that it is important to be aware of your body, your emotional state, and your mental state. I think this is good news for all of us, ”said Miller.
