      Why does this frighten me to the core. A donut is a tube, it makes sense but I hate this knowledge

        Depends on how you see it, a hole or a tube. I prefer a hole.

        A common joke is that a topologist can’t see the difference between a donut and a coffee mug because you can mould a mug into a donut (assuming it has a handle).
