    Of all of the cells in your body, less than 45% of them are human. The majority are microorganisms designed to work with your gross-ass self for similarly gross organic meat-bag processes.

        I actually looked this up just for you. Surprisingly low at .3%! While the number of cells are roughly halfish each human and non human, the non human cells weigh so little they only account for around 200 grams of actual weight. Learned something new myself there.

    Newborn baby girls can experience a phenomenon called “false menses” or “mini-periods” due to a sudden drop in maternal estrogen after birth, causing slight vaginal bleeding or a blood-tinged discharge that typically lasts only a few days.

      This works great with @Nomad@infosec.pubs tip regarding the flexibility of our tongues.

      Btw, the noses (so called becherocells) just create the slime (glycoproteins) to catch and bind bacteria entering from the outside, they (luckily) don’t create bacteria on their own.

      I’m fairly certain that if women would get a full disclaimer with all the nasty side effects a pregnancy comes with, they’d give it a second thought… On the other hand, some women insist on having a second baby… And then a third… And a fourth…

    Retrograde menstruation.

    Because the feliciano tubes aren’t closed on the ends, where they interact with the ovaries, blood from a period can flow backwards into your abdominal cavity.

    Additionally, a small amount of sperm (if a woman is sexually active and say trying for a baby) can also go the full way and leak into the abdominal cavity.

    So some women can have blood and semen free floating in their abdominal cavity. Between organs

    Edit: autocorrect got me. I meant “fallopian tubes”

        To avoid stickyness what you want to do is, since it’s a protein, freeze dry it with liquid nitrogen as soon as it exits the urethra and viola! no more sticky.

    Human face pores are home to tiny, microscopic mites called Demodex.

    They are most active at night, when they leave their follicles to mate on the face and then return to find a new follicle.

    Almost everyone has them. So there are tiny arachnids having sex on your face every night.

        It’s not an illness. In most cases they are completely harmless and unavoidable, you get them from your mom as a baby and carry them your whole life. Most people have them. A minority of people can have some skin condition due to them, but it’s quite rare. And yes dogs carry them too, but not an issue for them either.

    Its possible to stick your tongue inside your nose from inside your mouth. I am among quite a few people that can do it and clean the inside of the nose from boogers.

      Apparently if your tongue isn’t long or flexible enough, the Wikipedia has suggestions, ranging from months of flexing and tongue exercises, to just fucking snipping your frenulum.

      “It is possible” lmao, like yeah, it’s also “possible” to put my dick in my butt if I cut my ass off and hold it in front of me XD

      Usually these TIL threads give me nothing new.

      This one is new to me. Thanks.

      I’m at third stage! I’ve been hiding my tongue behind my uvula since I was a kid. My dentist hated it!

      I never thought of it as stretching… I guess I have a new hobby!

        Feels strange at first, then its very handy. Helps unclog the nasal passages. You can even suck on a side passage and spit out what comes out. I once had a piece of string from a corona mask stuck in a side passage and was able to get that out just with my tongue. its also a nice trick so groce out people xD

        Takes trying for a few days to stretch your tongue to get it far enough back.

    If you feed a latex tube through the nose and out the mouth then pull it back and forth, it makes a squeaking sound

    There are more cells in your body that aren’t you, than are.

    The count of bacterial cells in your gut, on your skin etc is higher than the number of your own cells.

      I’ve always found this interesting. Human beings (or any vertebrates I suppose) are really more of a colony than a single being. And it’s not just a technicality, it’s meaningful. Much of that colony interacts with your nervous system and affects your moods and behavior. You think you have total control of your mind, but you would think and act differently with a different balance of gut bacteria. Chew on that for a while…

      I think one’s microbiome has more mass than one’s brain too. So… who is really doing the thinking?

      This is one of the scientific plot holes in The Fly. Or at least the 1980s version. The head-swap version has other problems.
