Hold a piece of white paper up to your mouth the next time you yawn, and you'll notice a fine spittle that sprays out. I see so many people, children and adults, that do not cover their mouths when they yawn. Some don't even turn their heads. It isn't only coughs and sneezes that we need to worry about.
With school starting and flu season just around the corner, can I gently ask that we start exercising a minimal amount of courtesy when yawning? I can't tell you how many times a day I wipe off keyboards and computer areas in our school because of this.

Because we don't care if evil spirits invade our body that way. But seriously . . .

Because there is no force behind the "spray", and it doesn't spread beyond our personal space. Hold your piece of paper out at reading distance, and see if any of the spray reaches that far. A cough or a sneeze can propel particles 15 or 20 feet.

There's dry coughs and some sneezing that doesn't really go far at all much like the slight open mouth yawn, right before *most* people cover. In all fairness, sometimes those yawns can sneak up on ya.

Simple good manners are not thought much today so it's a wonder that people don't display more gross behaviors.

Oh, wait.....They do!!

Covering one's mouth when yawning is a manner's issue not a public health issue...

As already noted there is no forceful expulsion of droplets from a yawn...

I'm a germophobe and even I have no problem with people keeping their mouths open when yawning. Sure it would be more POLITE to cover it.
I'm more concerned about people sneezing and not covering their nose or coughing.

So do I, but only so people can't see how bored I am with whatever they are doing or saying.

I beg to differ. Some exhale quite forcefully. And then there's the issue of not-so-fresh breath being blown your way.......
