So, I had just eaten lunch and was going to meet my friend at the pool to swim. On the drive, I quick popped in a piece of gum giving no thought to it and threw it out when I got to the pool. Oh my goodness, that night I was
S T A R V I N G!!!! Even the next morning I was SO hungry! And then it occurred to me! Stupid gum.

When you chew gum, you salivate. When you salivate, a signal gets sent from your brain to your stomach that food is on its way, and you begin to produce gastrointestinal juices...then, the food never comes, leaving you feeling hungry - because you told your brain that food was on the way, yet it wasnt.
