Let's make this birthday one to remember.

40 years old (Born on September 14, 1984)

Happy Birthday, Caleb Campbell! From tackling opponents on the field to serving your country with honor, you've always known how to make an entrance. Who else can say they've swapped Army boots for NFL cleats and still kept their sense of humor intact? Your debut in 2010 with the Detroit Lions was legendary—proving once again that linebackers really do know best when it comes to surprise attacks.

Here's wishing you another year filled with victories both big and small. May your birthday be as memorable as those epic tackles—and may life continue throwing touchdowns right into your hands (or at least within easy interception range). Cheers!
