"That's because the International Olympic Committee has a policy of never replacing medals"

This quote by Mary Lou Retton is referring to the International Olympic Committee's policy of never ever replacing medals. This policy remains in place to make sure that the integrity of the Olympic Games is preserved. It is a method of honoring the professional athletes who have actually made their medals and acknowledging their effort and devotion. The policy also serves to prevent unfaithful and other types of dishonesty in the Olympic Games. By not changing medals, the International Olympic Committee is sending out a message that cheating and dishonesty will not be endured. This policy is a reminder that the Olympic Games are a location of reasonable competition and that professional athletes must make every effort to take on stability.
