                      Burping, sneezing, and blinking


                  might seem silly. But these functions


                  are important too.


                      Burping isn’t just a party trick.


                  People swallow air when they eat and


                  drink. Sometimes too much air gets


                  trapped in the stomach. The body


                  forces the air up. Burping lets it out.
