Let's make this birthday one to remember.

39 years old (Born on December 19, 1985)

Happy Birthday, Christian Sprenger! May your celebrations be smoother than your Olympic breaststroke and more coordinated than a perfect medley relay. We still remember that epic silver medal swim in the 100-meter breaststroke at London 2012—proof you can chase down anything (even cake) with style.

And let's not forget how effortlessly you helped secure bronze for Australia in the thrilling 4x100 meter medley relay. Clearly, teamwork makes dream work—and medals too! Here's hoping this birthday brings as much joy as standing on an Olympic podium—but without having to wear goggles or shave every inch of body hair. Cheers!
