Dust!!!!

Hey Cecil and Teeming Millions!
So tell me about dust. Are there different kinds of dust? Where does dust come from? Where does it go?
Thanks a lot!

90% of household dust comes from hairs fallen from the legs of spiders. And spiders, by the way, are surprisingly abundant in factory-produced chocolate. But I have no idea where dust goes.

I think it’s mostly shed skin from humans. But insect parts are a part of dust, according to Cecil.
