Let's make this birthday one to remember.

36 years old (Born on December 17, 1988)

Happy Birthday, David Rudisha! You're the only guy who can run 800 meters faster than most of us sprint to catch a bus. Your legendary gold medal at the London 2012 Olympics didn't just break records—it made everyone else look like they were jogging in slow motion!

From your epic victory at the World Championships in 2011 to setting that jaw-dropping world record, you've shown us all how it's done—fast and with style. May you celebrate today by outrunning candles on your cake or perhaps giving them an eight-hundred-meter head start first! Keep inspiring (and lapping) us all!
