The Right Way To Think

So the next time you see me yawn…..I am putting my analytical mind at ease……

Over the years, there have been many theories for why people yawn. It has been associated with sleepiness and boredom, and, incorrectly, with low oxygen levels in the blood.

“No one knows why we yawn,” says Andrew C. Gallup, a psychology professor at the State University of New York at Albany.

Now Dr. Gallup and fellow researchers have a new explanation: yawning, they said, is a way for the body to cool the brain.
