    My fave parts (edited for brevity):

    The adult mites are 0.3–0.4 mm (3⁄256–1⁄64 in) long. Each has a semitransparent, elongated body that consists of two fused parts. Eight short, segmented legs are attached to the first body segment. The body is covered with scales for anchoring itself in the hair follicle, and the mite has pin-like mouthparts for eating skin cells and oils that accumulate in the hair follicles.

    … and …

    The mites are transferred between hosts through contact with hair, eyebrows, and the sebaceous glands of the face.

    Ohhh good.

      Wait, 0.3mm is huge, you should be able to see that. I don’t think this is right.

        Maybe we do see them, but mistake them for bits of skin or dirt.

        Agreed. 1/64th of an inch is .016". An average human hair is .003" in diameter, that would be as long as five hairs wide. You wouldn’t even need a magnifier to see the largest ones.

        Combine the size with the fact that they are semi transparent and live in hair follicles and sebaceous glands, both of which are essentially under the skin, and that’s why you don’t generally see them.

      3⁄256

      Please don’t let the Amish at my work know that such small increments of size exist. They’ll ask me to cut my trim to that level of tolerance

      This is why it’s okay to make out with randos at parties and such. You get mono for 6 months plus accretion of zillions of new friends.
