Let's make this birthday one to remember.

43 years old (Born on March 25, 1982)

Happy Birthday, Mark! You're the only guy we know who can switch from tea to mate without missing a beat. Whether you're scoring goals for England or making waves with Argentina, your water polo skills are legendary—rumor has it even dolphins take notes when you play!

From epic international matches to unforgettable victories, you've made quite a splash in both hemispheres. Here's hoping this year brings more thrilling moments and fewer accidental poolside belly flops.

Keep swimming strong and laughing louder than ever—cheers to another fantastic lap around the sun!
