  Fun fact: humans are geometrically a donut.

    I’m sure most people have more (topological) holes than one

    Both nostrils, for example

      The nostrils are connected to the throat through the sinuses as are the ear canals. Topologically making them all part of the same mouth-anus throughole.

        Not true, topolgically the route

        left nostril -> sinus -> right nostril

        is another hole. So is

        any nostril -> sinus -> mouth.

        ears have the eardrum, so they don’t count.

        For the more formal definitions of topological holes, look up Betti numbers. What we’re currently talking about is the Betti number b_1. For humans, that is at least 3 (but I’m sure I’m missing many more holes). Unless you’re missing the entire septum.
