Let's make this birthday one to remember.

41 years old (Born on February 29, 1984)

Happy Birthday Cullen Jones! You swim through birthdays faster than most people sprint freestyle. With your Olympic gold medal in hand and countless fast finishes behind you, getting older must be no big deal—you've clearly mastered speed both in the water and on land.

From anchoring Team USA to victory at the Beijing Olympics, bringing home shiny medals from London 2012, to inspiring swimmers everywhere with each stroke you've taken—your outstanding performances have left a ripple effect (pun definitely intended!). Here's hoping this next year races past smoothly as ever—with fewer chlorine-scented cakes but plenty of new victories ahead.
