Let's make this birthday one to remember.

46 years old (Born on February 28, 1979)

Happy Birthday, Ivo Karlovic! The man whose serve is so powerful, opponents often wonder if they're playing tennis or dodging missiles. Your towering presence on court has always been matched by your legendary wit off it—proving that height isn't just an advantage in tennis but also in delivering punchlines.

From setting records with aces to defying age barriers by competing fiercely into your 40s, you've shown the world that birthdays are merely numbers—just like the countless aces you've served. May your day be filled with laughter and joy, and may you continue serving up greatness both on and off the court!
