Dogs yawn as well, and it doesn’t only mean that they are tired, more like “I try my hardest to stay concentrated, but is really hard right now”

You're not tired, but you saw a post about yawning? Well, guess what.
You are now yawning manually.
When a baby is crying on an airplane during takeoff or landing, I visibly and audibly yawn in front of them on purpose, so they catch the yawn and pop their ears.
that is genius
You're supposed to stay in your seat during take off and landing. Please, remain in your seat. Why do you keep getting out of your seat and silently scream at the babies?!
Who says you have to get out of your seat?
How to tell if your baby is a sociopath with this one simple trick. For this trick you'll need: a baby, a stranger, an airplane, and the power to suspend all critical thinking.
Wtf
Just reading this made me yawn.
same! what is this WITCHERY!?1
oh gods dammit fuck aaaaall y'aaaaaall.
Yawn
Apparently there isn't much consensus on what the actual reason(s) are for yawning. Apparently fish yawn though, so that's cool.
Isn't it a social signal, apebrain talking?
Solitary animals yawn too. Don't if they can catch yawns, or how to test it.

It seems like it helps the brain switch modes (from low activity to high and from high activity to low). So yawning could help prepare the brain to pay attention to something important, as well as wind down for the evening. Hence both morning and evening yawns.
The contagious aspect could be as simple as "Oh, you're changing modes? I should get ready to do the same."
Are there any other involuntary social signals?
….erections?
I do prefer to let my erection do the talking.
^ -me to the police officer who pulled me over and asked if I knew how fast I was going.
Name checks out

What's that? You're not tired and you haven't seen anyone open their mouth big, but you read about a hypothetical person opening their mouth big? Bad news...
Luckily I managed to cover my yawn but keeping my lips/teeth together but opened up the inside of my mouth. Think I got away with it.
Careful, I literally pulled my neck last week doing that
You read the word Yawn several times in a meme, guess what
Literally just yawned reading this meme, lol.

You saw an animal open their mouth big? Have fun.
Co2
Isn’t the leading theory that yawning is more about cooling down the brain temp rather than a lack of oxygen or buildup of CO2?
Yeah, you are correct. There are several reasons. :)

You hit the gym and are having a good session, guess what
This. I have started to wonder if yawns are actually a way to wake up. We know little about them. Some brain scans showed that we refresh the blood around our brain, like changing the water in a fish bowl.

This post literally made me yawn. Not because it's bad either.
Snake yawns are the most cute of yawns and I will fight every one who says otherwise.
My idea is that yawing helps sync our internal clocks. So, we sleep at the same time, and wake up at the same time. That way, no one is left behind when the group starts moving to the next waterhole, or feeding ground.

A yawn is a signal to regain some alertness, so when you yawn in order to become more awake, it signals your fellow life forms they might want to be alert too. 🥱
What? You're hungry? Well, I'll just make you yawn
Didn't have to see anyone, I've done it twice just reading this post.
Edit: 3 times cause I was checking back.
Got to make everyone tired so they don't get you while you sleep.
🥱
I saw someone recently yawn at a zoom meeting, and I thought "rule."
