Let's make this birthday one to remember.

38 years old (Born on January 15, 1987)

Happy Birthday, Alexander "The Mauler" Gustafsson! Another year older, but still quick enough to dodge birthday punches better than you dodged opponents in the Octagon. From your epic battle against Jon Jones at UFC 165—still considered one of the greatest fights ever—to dominating performances that earned you the top spot in UFC's light heavyweight rankings back in January 2014, you've always shown us how it's done.

May your cake be sweeter than victory and easier to handle than a five-round bout. Here's hoping this year brings more knockouts (in life!) and fewer bruises. Keep fighting strong, champ!
