musk believes we're living in a simulation, so I'm sure we don't.
In my opinion it's the modern "explain what cant be easily explained with gods"
It also helps them being inhuman and cruel, because it's a simulation anyways, right?
It clears your sinus / ear tubes, useful for pressure equalization even when walking mild elevation changes
Probably at least somewhat related to that somehow I bet
Does it also help reticulate my splines?
Then why contagious?
Monkey see, monkey do.
But my pets yawn when I yawn
Nice pet monkeys you've got there
neither is sleeping - nor dreaming. sleep is still such an interesting and elusive thing.
i've recently fallen into what i can only hope is a trap. i think i'm already dead, and this experience is just me remembering my life.
oh hi DP/DR.
oh no there's a wikipedia article. i'm not going to get any sleep tonight
I thought I'd read that yawning is just to help boost your oxygen levels, but I don't have sufficient motivation to actually look it up.
That's easy to check. I'm currently insanely jet lagged and super tired, yawning every few minutes. My pulse oximeter is indicating 99% saturation, so that's not it.
Edit: on the other hand, I'm a flight attendant, so my body is used to lower oxygen atmospheres, so I usually have >98% O2 levels.
Maybe you're at 99% because you've been yawning?
Ok, I am sufficiently caffeinated and bothered to look up a study: https://pmc.ncbi.nlm.nih.gov/articles/PMC3678674/
According to the above, they suspect it has to do with helping to keep you relative alert/awake but also, possibly to cool the brain and adjust ear pressure.
Yawning is for getting more air when you don't have enough.
Yawning also has a social effect, which is why it is "contagious"
If a big part of the tribe gets tired, then everyone will want to rest.
Many many animals yawn. Not just mammals but birds and reptiles. Even if we don't understand fully why something happens, seeing it throughout the tree of life like that probably means there's some reason for it.

Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
