Uzbekistan's Chusovitina not ready to call it quits

Uzbekistan's 41-year-old Oksana Chusovitina still enjoys competitive gymnastics and is even eyeing the 2020 Tokyo Olympics, which would be her eighth Games.

After finishing seventh in the vault final in Rio on Sunday, she received a message from her teenage son.

"He said he was proud of me," said Chusovitina, who has kept prolonging her career in order to provide for her son and herself.
