      It also only has one hole, which, if you ask some topologists, is what humans have.

            I would post the human floss video. But it seems to be lost media. It was of a guy who got extra strength floss, tied it to one of his teeth, and one end to a pen lid… Swallowed the entire roll. Found the lid days later, and then pulled it back and forth, to floss himself. The video would be +10 years old.

              Seems dangerous. There are sections where you wouldn’t want the floss pulled taut, and certainly not the whole thing.

              I wonder if it was just a magic / fx video; at least the “to floss himself” bit.

                I just remembered the name. But searching it up just gives reddit posts with dead links. It was called “full body floss.” All the the youtube links are dead. But I wouldn’t recommend trying to do.

          Well, there’s the one obvious one - mouth through to the anus, there may be more openings to that hole, but I don’t believe any of them go all the way through.

            That changes the topology though. It does go all the way through a section which prevents it from reshaping into a straw/donut

              They go through the same hole as the mouth in the end, though. At least a part of them…

              I think I said in another comment that I’m not an actual expert on this matter. So there may well be more holes in this theory, and person.

                Yes, but they’re distinct openings, which means we’re not topologically equivalent to a doughnut when you take them into account. Topological equivalence implies that you can transform one object into another without changing the number of openings. Classic example is a doughnut and a coffee mug (the handle of a coffee mug is the opening). A human would be equivalent to a doughnut with two holes poked through the side into the middle.
