Let's make this birthday one to remember.

50 years old (Born on January 07, 1975)

Happy Birthday, Ivan Calderon! You're the only guy I know who can defend a title 11 times without breaking a sweat—or growing an inch taller. Your legendary moves in the ring made opponents dizzy and fans ecstatic; rumor has it they're still trying to figure out how you danced circles around them.

From your epic reign as WBO Minimumweight Champion to becoming Puerto Rico's pride with every swift jab, you've proven that greatness comes in small packages—especially when wrapped up like dynamite gloves. Here's wishing you another year of knockout moments (minus any actual punches). Keep bobbing, weaving—and celebrating!
