The conventional idea that yawning is a sign of tiredness or boredom is now thought to be incorrect.

Quote

Instead, yawning may actually be about regulating the temperature of the brain. Like a computer, the brain operates best within a certain range of temperatures and when it gets too hot a good yawn can help to cool it down, promoting clearer thinking.

I read somewhere that yawning was also the cause of one's body requiring a boost of oxygen in the blood stream. I wish I could remember the article in question.

I yawned twice while reading the article.

In the beginning there were only probabilities. The universe could only come into existence if someone observed it. It does not matter that the observers turned up several billion years later. The universe exists because we are aware of it.

I read somewhere that one yawns as an attempt to stay alert when one is bored.

All this reminds me I have a cat that yawns continually whenever you scratch his head.  My other cats don't do that.  I doubt that it can be explained beyond "different cat," but it is interesting.

That's what I have heard/read as well. Nothing to do with boredom.

A little trick you can pull on a car load of people or a gathering of people is to yawn, wait a bit and yawn again. If you repeat this enough before long several people will start to yawn. LOL

I think you mean uvula but if they want to show the other bits it is fine by me  :clap:

Believing when there is no compelling evidence is a mistake.  The idea is to withhold belief until there is compelling evidence and if the universe does not comply with our predispositions, okay, then we have the wrenching obligation to accommodate to the way the universe really is.  - Carl Sagan

That which can be asserted without evidence can be dismissed without evidence. - Christopher Hitchens

I buy yawn vacinations every morning, they last 5 hours and taste like fruit.
