Let's make this birthday one to remember.

49 years old (Born on September 15, 1975)

Happy Birthday, Tom Dolan! You're the only guy we know who can celebrate by swimming laps around everyone else—literally. From your legendary gold medal swims in the 400M individual medley at both Atlanta '96 and Sydney 2000, you've proven that chlorine is your cologne and Olympic podiums are your favorite hangout spots.

Even though it's been a while since you dominated the pool, your legacy still makes waves. May this birthday be filled with laughter, joy, and absolutely no butterfly strokes (unless they're on cake frosting). Here's to another year of being faster than most fish—cheers to you!
