NEW YORK (Reuters) - Swimmer Dana Vollmer has beaten the odds before and the American is displaying her inspiring heart again in a comeback quest for more Olympics hardware at this year's Rio Summer Games.
Vollmer, who overcame heart surgery as a teenager to win gold at the 2004 Olympics, and set a world record on the way to winning the 100m butterfly at the 2012 Games, aims to show she still has what it takes after giving birth last year.
