Let's make this birthday one to remember.

46 years old (Born on March 10, 1979)

Happy Birthday, Ashley Callus! You're the only swimmer we know who can claim Olympic gold and bronze medals in freestyle relays—and still look good wearing goggles. From your legendary splash to victory at Sydney 2000, where you helped Australia clinch that unforgettable gold medal moment, you've been making waves ever since.

Eight years later in Beijing 2008, just when everyone thought you'd peaked (or maybe dried off), you dove right back into glory with a brilliant bronze performance. Clearly age is just another lap around the pool for someone as timelessly talented as yourself!

Here's wishing our favorite aquatic legend an amazing birthday—may it be filled with laughter and cake that's sweeter than chlorine-free water!
