Consider the human gastrointestinal tract. Technically it’s not part of our “insides” even though it passes through us.
It’s more like the hole in a donut that passes through the donut.
Looking at a donut, think of the top of the donut hole as your lips and the bottom of the donut hole as the hole in your bottom. Stretch that donut vertically until it’s about six feet tall. Along the way, feel free to extrude pairs of arms, legs , and ears, and whatever else you’d like, from the glazed outside of the donut. What should this thing be called?
A few years ago, a French pastry chef in NYC started making donuts out of croissant dough and called them “cronuts.” I’m calling my human inspired donut a “bronut.” It’s catchier than saying “sapiennut” or something like that. Mathematicians call the donut shape a “torus” but that’s not evocative enough.
Anyway a bronut is just a way to envision something that’s in us but at the same time also not part of us .
