Let's make this birthday one to remember.

49 years old (Born on March 25, 1976)

Happy Birthday, Wladimir Klitschko! You're the only guy we know who can blow out birthday candles with a jab. With IBF, WBO, and IBO heavyweight titles under your belt (literally), you've knocked out more opponents than most people have candles on their cake. Your legendary fights have inspired millions—though we're pretty sure your opponents still flinch when they hear your name.

Even though you've stepped away from the ring, you're still undefeated in charisma and class. May this year bring you as much joy as all those championship belts brought you glory—and fewer bruises! Cheers to another round of greatness!
