Let's make this birthday one to remember.

41 years old (Born on July 10, 1983)

Happy Birthday, Gleison Tibau! You're the only fighter who can step onto a scale and make gravity nervous. Ever since your UFC debut at UFC 65 back in November 2006, you've been defying physics—shrinking overnight to dominate opponents half your size by fight night.

Your legendary weight-cutting skills have become MMA folklore; rumor has it even saunas fear you. Here's wishing you another year of success both inside and outside the octagon—and may all birthday cakes magically weigh zero pounds on weigh-in day!

Cheers to more victories, fewer scales, and endless laughs today—you've earned them all!
