Beginning our list of 21  cool but pointless facts about the human body is something that you probably already know. Yawning is contagious.

Yawn… Why did I do that? Why did I just trigger a yawn in you? I did it to demonstrate a cool experiment. What experiment? Yawning is contagious. It really is, but there’s a fair chance that you already know this. But why is it contagious?

Don’t you just hate looking at someone yawn and then getting the urge to yawn yourself? It’s extremely annoying if I do say so myself. When the reflex is triggered in me by the actions of another, I’m not even tired. To tell you the truth, I’m generally not tired, or bored. But despite this fact, when I see another person yawn I follow suit, as if it’s the latest trend. But the freaky thing is, if I see an animal yawn, I will too. So why?

Do you know what a yawn is? A yawn is a reflex of simultaneous inhalation of air and stretching of the eardrums which is followed by an exhalation of your breath. It is usually associated with tiredness, boredom, exhaustion, stress or being overworked. But despite all these reasons for yawning, there is one other. Yawning is contagious. It’s so contagious that about 50 percent of people reading this right now have already yawned, or are about to yawn.
