37 years old (Born on January 21, 1988)
Happy Birthday, Ashton Eaton! You're officially another year older—but let's face it, you're probably still faster than most of us on our best day. From your jaw-dropping Olympic gold medals to setting the world record in heptathlon and decathlon (seriously, who does that?), you've made running around a track look way too easy.Here's hoping this birthday brings you as much joy as crossing the finish line first—or at least more cake than hurdles. May your celebrations be filled with laughter and fewer ice baths; after all those legendary performances at London 2012 and Rio 2016 Olympics—you've earned it!
