To be honest, part of me never grew older than 12. And I honestly believe that a lot of adults have the same questions they had when they were 12, only now they are either “too busy” or “too adult” to ask these questions. For example, why does your stomach growl when you are hungry? Well, look no further:
Basically, the involuntary muscle movements that push food through your digestive tract keep working even after most of that food has moved on down the line. Eventually, gas bubbles are all that’s left to be squeezed, and you get a rumbling sound as they pop. It’s part of how your intestine keeps itself cleansed—no expensive pills or powders required!

What do you say to that, eh? I bet you always wanted to know that.
