    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.
