Happy Birthday, Kenenisa Bekele! You're the only person we know who can make running 10,000 meters look easier than blowing out birthday candles. With two Olympic gold medals in the 10,000 m and another shining victory at the Beijing Olympics' 5,000 m race in 2008 (though we're sure you could've won it again if they'd let you run backwards), you've truly set records that leave us breathless—literally.As you celebrate today, remember: age is just a number—and you're pretty good with numbers like "26 minutes" or "12-and-a-half laps." Keep inspiring us all by chasing greatness faster than most of us chase cake slices. Happy birthday to Ethiopia's legendary long-distance king!
