If you put fresh shit in a closed box, it will still stink up the whole room, but the shit in my ass will barely stink even if my ass is on your face, although there is a hole there. Why

      Otherwise we’d all constantly smell like fart. Cause a fart is just opening that hole and pushing air out.
      (… or maybe we do smell like fart constantly and just don’t know cause we don’t smell smells that constantly hit our nose)

    They still stink if you let some air through by farting. Boxes are rarely airtight, whereas assholes usually are.

    Source: I have a plastic box that I often put some acetone in. And sometimes I fart. The two are not related.

    Your asshole isn’t just open all the time. And even then, there are a couple of gates (sphincters) that prevent a straight through passage from your bowels to the outside of your body.

      And the rest of your body is reasonably water proof and gas proof. Whatever is on one side of a membrane, is not allowed to cross to the other side. Actually, your body is working hard to keep it that way. If something is allowed to cross that border, it’s an exception and it’s highly regulated.

    I appreciate your presence on this website a lot and that’s a genuine sentiment. Most of your other posts are pretty bleak (and I appreciate them too) but this one got a good giggle out of me xD “Why” lol

    If your body was like a shoe box you would bleed to death. put shit in a ziplock back and then a cooler and you would be hard pressed to notice a smell for days.

    If you leave your mouth open for long enough, you break the vacuum holding the shit and piss stink in and you’ll start smelling.

    Sphincters and seals: they do a good job! Not fun to think about, but that’s why when someone shits their pants, or dies and voids their bowels, it’s immediately obvious.

      Sphincters are important for other things too. It’s basically any muscle that forms a ring. While anuses (anii?) are obvious use cases, you also have one between your stomach and intestines, and one in each eye. Probably other places too.

      I heard a paramedic from a tv show says dead people cant fart because they need to be able to clench their asshole to release it, but i dont get how they can void their bowels since you pretty much need to be able to do the same thing to shit it seems

      Unless they ate enough to literally be full of shit that has to come out. Not sure if theres still peristalsis upon death eitherk

        They wouldn’t day because everything would be open so there’d be no pressure to shoot a fart out of. Why gasses would be slowly released as death relieves pressure on the sphincters and let’s go. I imagine because of gravity and not being alive too keep muscles and whatnot on the correct places for normal function will just let all of your shit out too. It’s not that we need pressure to let shit out, but we use pressure to get it out in one go and we do so with many “airlocks” so we only lose what we need at that time.

        This is mostly me talking out of my arse but it sounds right to me as i type it. I imagine i don’t have the specifics down but maybe the general gist?

    Not smelling like excrement would have been a significant advantage for most of human history & our ancestors before that where we had predators hunting us and conflicts with other humans where hiding would have been a good defense tactic. Animals that do have strong scent usual are a deterrent for predators or territorial predators marking their territory.
