Above is a manly picture of Demetrius Jonson, the first and so far only Flyweight Champion of the UFC. At only 5’3”, he fights at 125 pounds, but I can say with confidence that for 99.99% of the people reading this, “Mighty Mouse” would knock you unconscious, or choke you unconscious, without breaking a sweat.

In fact, that number may very well be 100%. Demetrius Johnson is near the top, if not at the top, of most lists of greatest fighters, pound-for-pound (meaning comparing all weight classes) of all time. (He is at the top of the official UFC rankings and also Sherdog’s #1 in the world) He is a master of multiple martial arts, and a master of combining those martial arts with blinding speed and near-perfect technique. Here’s a highlight reel that gives you an idea:

So, what kind of person would you expect to be a fighting machine? Some kind of alpha-male dude-bro maybe. Someone with a chip on his shoulder and a criminal record who lives a life of excess and thrill-seeking behavior.

In stark contrast, here is what Demetrius Johnson does when he’s between training camps or in recovery:

Yup, that’s a Twitch stream. This master of world-class ass-kicking is a gaming nerd. He’s also seemingly quite a family man, with his wife, Destiny, and two small children. He had a tough upbringing, born premature and raised in an abusive household, but he has also worked hard to overcome that beginning, and has seemingly reached the pinnacle of his chosen endeavor. Which, again, is fighting other men in a cage.

For comparison, I think of Jon Jones, the current Light Heavyweight Champion of the UFC and another incredibly talented martial artist. He’s up there next to Johnson on the pound-for-pound lists. But in contrast to Johnson, Jones has had multiple issues with illegal drugs, banned performance-enhancing substances, a hit-and-run accident, and a lot of behavior that has hurt himself and those around him. Meanwhile, Johnson hangs out with his family and plays video games and is a clean fighter who lives a clean life.

For his toughness (he has fought with multiple broken limbs over the course of his career), devotion to his family, enjoyment of hobbies that are not usually associated with a fighter’s life, as well as avoiding the many moral pitfalls that come with fame in an ultra-masculine environment, Demetrius Johnson is this week’s Profile in Positive Masculinity.
