Olympics: Simone Biles leaves with a medal and a message

For 72-odd seconds, Simone Biles is somewhat her old, assured, balanced, competitive self. For 72 seconds she's focused on a balance beam 5m long and 10cm wide. For 72 seconds she's not a curiosity, a debate, a role model, a hate figure.

For 72 seconds she's just a gymnast trying to be flawless.
