As far as I know, the purpose of yawning isn’t really understood, but it’s present in nearly all land vertebrae. Maybe it’s a universal bug in the breathing animation code.

    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?

    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.

    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.

      Woof. I dread to think that I would remember in such precise detail all the dozens of lemmy posts and comments I’ve read this morning. But it’s quite a thought!

        i can’t quite describe the intensity of the horror. it’s like a dream where you can’t run, but at time same time someone’s forcefully twiddling a finger on your precious in-between. it’s a scream you just can’t type.

        Can you really recall every single detail? I’m not sure about you, but I can easily spend 30 minutes reading comments and then forget exactly what I was reading. Could I be reading gibberish that feels meaningful in the moment, but is gone as soon as I move on? Kind of like a dream?

    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.

    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.

          The thing is that my o2 saturation doesn’t drop between yawns, which is what leads me to believe that’s not it.

            Yeah, there doesn’t seem to be anything (at least in that study) to suggest it actually impacts blood oxygen levels either.

      Smog is just the developers’ workaround for overpopulation because the universe machine can’t handle that many animated entities without distance culling.
