Let's make this birthday one to remember.

54 years old (Born on October 13, 1971)

Happy Birthday, Sean O'Donnell! Another year older and still skating circles around the rest of us. Your legendary toughness on defense made you a Bruins favorite—fans still reminisce about your gritty battles and epic penalty-box visits like they were yesterday.

From delivering bone-crushing hits to hoisting the Stanley Cup with Anaheim, you've always been a class act both on and off the ice. Here's hoping this birthday brings fewer bruises than your hockey days—but just as many cheers! Keep being awesome, Sean; you're proof that age is merely how long you've been sharpening skates. Enjoy your day!
