Let's make this birthday one to remember.

44 years old (Born on September 03, 1980)

Happy Birthday, Jason McCaslin! You're the bass wizard who kept Sum 41 rocking through countless epic shows and unforgettable albums. From your energetic stage presence to laying down those iconic bass lines, you've proven that pop punk isn't just music—it's a lifestyle. And let's not forget "Complicity," your tenth album masterpiece from 2013; it still resonates louder than ever!

Here's hoping this birthday is as legendary as your career has been so far. May you continue slapping the bass with youthful rebellion and timeless style for many more years ahead—because honestly, what's our age again? Rock on!
