Let's make this birthday one to remember.

39 years old (Born on July 24, 1985)

Happy Birthday, Aries Merritt! You're the only guy who can sprint faster than most people run away from responsibilities. Ever since you hurdled your way into history at the 2012 London Olympics—winning gold and setting a blazing world record in the 110-meter hurdles—you've made jumping over obstacles look easier than blowing out birthday candles.

Here's wishing that this year brings even more victories (and fewer hurdles off-track). May life continue to reward you with success as effortlessly as you've cleared barriers on race day. Keep inspiring us all by leaping gracefully through life's challenges—and remember: cake calories don't count when you're an Olympic champion!
