    It’s even better than that. There’s a vsauce video that talks about what a hole really is and then abstracts the human body down to its holes. I think there’s like 7 iirc. 2 nipples, 2 tear ducts 4 holes in the eye near the tear ducts, 2 nostrils and your mouth

    Edit: correct holes lol

        Anus is connected to the mouth. Urethra isn’t a through hole I don’t believe…could be wrong though.

          Tear ducts are connected to the nostrils. I really don’t get what the criteria for “hole” is, here.

            It’s the topology of the object. Essentially flatten the object into a 2 dimensional plane. Something like a mug or donut will have a hole in it after flattening, these items have 1 hole. Different objects flatten into a different number of holes. It’s really hard for me to parae anything more complicated than 1 hole with my head, but that’s essentially the process.

            I do not recall the vsauce video explicitly, but this should be the logic they’re using. It gets waaay more difficult to parae on something like a human, with a bunch of different tracts and splits and shit.
