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.
They go through the same hole as the mouth in the end, though.
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.

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.

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

Yes. I’m afraid I’m not a real topologist, so we’re at their mercy. Let us pray they don’t come up with new holes.

But you are topologically equivalent to one!

Donut be afraid my fellow fleshtube.
