The human body is a mysterious thing.
We do things all the time like yawning, sneezing, and stretching, without even thinking about them. Even if we don’t take the time to wonder why, scientists do. They spend their time studying the body and its many behaviors, and they have answers to some of the most common questions. Here’s what happening when your body starts doing its own thing.
