Let's make this birthday one to remember.

64 years old (Born on September 01, 1960)

Happy Birthday, Karl Mecklenburg! You're the only linebacker who could tackle quarterbacks and birthdays with equal enthusiasm. From dominating offenses in three Super Bowls to earning six Pro Bowl selections, your legendary career still inspires Broncos fans everywhere.

Even though you've hung up your cleats, we bet you can still blitz a birthday cake faster than most rookies run their 40-yard dash. May this year bring as much joy and excitement as those unforgettable Sundays at Mile High Stadium—minus all the bruises!

Cheers to another fantastic trip around life's end zone; keep tackling each day like it's fourth-and-goal!
