Did you know …
That mucus didn’t exist until the 18th century? It’s true!
Apparently, before then “mucus membrane” was just regular tissue, except maybe a little more damp. But in the 1760s, some Dutch alchemist invented mucus, and it just spread everywhere. Some kind of “ice-nine” bullshit.
I guess I’ve always lived in a world with mucus, but sometimes I think it’d be better if that alchemist had been eaten by an alligator or gotten some kind of brain parasite before he ever invented mucus. But c’est la vie, right?
