Let's make this birthday one to remember.

48 years old (Born on January 26, 1977)

Happy Birthday, Justin Gimelstob! May your day be filled with more aces than double faults and enough cake to rival the sweetness of those 13 career titles. Remember when you soared up to World No.18 in doubles back on May 8th, 2000? Clearly, you've always had impeccable timing—both at net volleys and birthday celebrations!

Here's hoping this year brings as much excitement as a fifth-set tiebreaker but without any unforced errors (like forgetting where you put your keys). Keep serving life’s challenges away like they're easy overhead smashes; after all these years off-court, you're still winning every match point!
