Let's make this birthday one to remember.

53 years old (Born on March 23, 1972)

Happy birthday, Joe Calzaghe! You're still knocking the years out with knockout style—undefeated boxing legend and undisputed champion of looking forever young. Your swift moves in the ring were only matched by your ability to dodge aging, proving once again you're unbeatable whether it's fighting Bernard Hopkins or candles on a cake.

From holding world titles in multiple weight classes to retiring unbeaten after 46 victories, your incredible career gives all of us reason to celebrate every year. Here's hoping your fists remain lightning-quick enough—to jab through gift wrap—and agile enough for cake cutting duties! Cheers, champ!
