Burping is not something one normally likes to do in front of others, even if it is natural for all of us to do. Did you ever wonder why our bodies have this kind of function?
A person person's body is an amazing machine; give it food and water and it takes care of everything else itself. For jobs like breathing and breaking down the food we eat, our bodies do all the work without our even having to think about anything.
However, what goes in must come out. This is true for the food and drinks we take in, which is why we need to go the bathroom several times a day. This is also true for the air we take in. Of course,having air in our lungs is necessary. Nevertheless, when a person gets too much air or gas in his or her stomach, there is a problem. Whenever we eat or drink, even when we chew gum, we take air into our stomachs Gas is also produced by the bacteria we have in our stomachs that break down the food we eat. When there is too much air to fit inside our stomachs, we need to let some of it out. Your body needs to let out this extra gas constantly-at least ten to fifteen times a day. Most of the time , this happens slowly and naturally, and we don't even notice it. However, sometimes it comes out all at once, which is when we have to say, "Excuse me!"
Although burping natural,there are some people who practice to develop better skills at burping. Take Paul Hunn from the United Kingdom, for instance. He is in Guinness Book of World Records for his burping. In September 2008, he set the world records for the loudest burp-107.1 decibels (db)! To put this number in perspective, 15 db is equivalent to the noise of a soft whisper. On the other hand,110 db is equivalent to the noise of a rock concert!
