Let's make this birthday one to remember.

49 years old (Born on September 28, 1975)

Happy Birthday, Lenny Krayzelburg! May your day be smoother than your legendary backstroke glide and brighter than the shine of those four Olympic medals. From setting world records in the 50, 100, and 200-meter events to making waves at Sydney's unforgettable Olympics—your achievements have left us all breathless (and slightly jealous).

Even though you've hung up your goggles competitively, we know you're still swimming circles around everyone else when it comes to style. Here's hoping this year brings you as much joy as that moment atop the podium—and fewer chlorine-filled mornings! Keep splashing through life with humor and grace; happy birthday champ!
