On the left, you can see what Nate Diaz's face looked like before his UFC on Fox 5 main event bout against Benson Henderson. In the poster for the event, Diaz is sporting a perfect pre-fight mean mug. On the right is Diaz after the fight. That's what he looks like after five rounds in the cage with the champion. He's smiling but his face is swollen and beat up. If you're considering trying MMA, take a look at the two faces of Diaz. You have to be ready for your face to make this kind of change.
