The results from the 2011 Nathan's Hot Dog Eating Contest tell us that Tim "Eater X" Janus is the third-best hot-dog eater in the world. He owns world records for speed-eating burritos, sushi, and ramen noodles.

All the training for that helped him develop another skill: In June, Janus became the burping champion of the world. He belched, uninterrupted, for exactly 18.1 seconds. Accordingly, we have produced this helpful video for you, as part of our Lifespin series, in which we teach you how to do something useful and relevant. Today: how to burp like a champ.
