Personally I find it pretty neat that as megafauna we are host to entire little ecosystems. It's a calming thought to imagine yourself like some large tree, home to little families of various creatures, bacterial and fungal colonies growing on you. We are thoroughly integrated into the ecosystems in which we live.

They're not harmful, they're just living their mitey little life.

I, personally, am wholly against most of my DNA existing solely it can replicate itself. So what if getting rid of it is more effort than keeping it? I want it gone from my body. Goddamn freeloaders...

[-] TankieTanuki@hexbear.net 4 points 3 weeks ago

Pretty much everything looks horrifying on a scanning electron micrograph.

https://en.wikipedia.org/wiki/Demodex

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.

[-] Maalus@lemmy.world 23 points 3 weeks ago

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

[-] MeowZedong@lemmygrad.ml 8 points 3 weeks ago* (last edited 3 weeks ago)

0.3mm in length, not diameter. Yes, you can see them, but they just look like dead skin/gunk to our eyes.

[-] jabathekek@sopuli.xyz 4 points 3 weeks ago

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

[-] Krackalot@discuss.tchncs.de 2 points 3 weeks ago

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.

3⁄256

Who uses inches at this scale? I mean, really, Wikipedia.

"Hand me my 1/256th inch ruler." --nobody

[-] brown567@sh.itjust.works 2 points 3 weeks ago

I learned recently that machinists used to use fractions to indicate tolerance, like a dimension given as 5/16 could be ±1/32 of an inch, because anything less than 9/32 would round to 4/16, and anything more than 11/32 to 6/16.

[-] jawa21@lemmy.sdf.org 3 points 3 weeks ago

It can still happen, but usually at the customer's request/requirements. We actually use inches at a much smaller scale, but use decimals instead of fractions.

[-] Classy@sh.itjust.works 4 points 3 weeks ago

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

[-] unemployedclaquer@sopuli.xyz 1 points 3 weeks ago

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.

Found out about these when I was a kid. I was thrilled. When I was very little, my mom owned a grooming shop, and I basically had 1 million pets. Then she closed down, and we just had our dog and a cat. Weird little 5 year old me loved the idea that I had thousands of little pets that's slept on my face and came out to play while I slept

[-] TrickDacy@lemmy.world 21 points 3 weeks ago

That's the best possible reaction to this :)

[-] dharmacurious@slrpnk.net 4 points 3 weeks ago

I will admit that since I've started wearing glasses, my eyes often burn really badly (I don't know if they're related or just weird timing), and I sometimes wonder if my little friends are pissed about the change and getting into my eyes. Lol

[-] june@lemmy.dbzer0.com 6 points 3 weeks ago

You may be allergic to the metal (IIRC nickel) in normal metal glasses if that's what you have. For people with that, which is common, titanium is the only metal kind that will work.

[-] dharmacurious@slrpnk.net 1 points 3 weeks ago

They're from Zenni, but they have no bottom frame. I have no idea what metal they're made of. I'd really never considered that

[-] june@lemmy.dbzer0.com 2 points 3 weeks ago

Almost all contain nickel and nickel allergies are common. I have it!

[-] Kyatto@leminal.space 3 points 3 weeks ago

I figure you'd also have a rash if it was a sensitivity strong enough to make your eyes burn, but the only other things I could think of I feel you'd already have figured out... Not blinking enough cause no wind on your eyes to help trigger blinking, eyelashes getting in your eye, or eye fatigue from the correction and not taking breaks to look at something far away..

Maybe you're allergic to something in your glasses

[-] dharmacurious@slrpnk.net 1 points 3 weeks ago

That's interesting. I hadn't really considered that. It really only happens towards the end of the day, I just assumed it was a buildup of oils/skin cells/daily detritus that isn't getting either blown away by air, because the lenses are blocking it, or dried out for the same reason. They're Zenni frames and lenses

[-] Classy@sh.itjust.works 3 points 3 weeks ago

Do you wear a belt? Do you develop a rash on your underbelly where it touches the buckle?

Can you guess how I learned I was allergic to nickel?

[-] dharmacurious@slrpnk.net 1 points 3 weeks ago

Nope, no rashes that I've noticed. But I stopped wearing a belt last year. No good for my body shape. Lol. Swapped it for suspenders, so now I look like a simple country lawyer. Lmao

[-] southsamurai@sh.itjust.works 29 points 3 weeks ago

Little homies up in there cleaning things and living their best lives. I ain't mad at that.

Besides, all the yeast and bacteria maken good company for them, so it's all good.

[-] Cenotaph@mander.xyz 10 points 3 weeks ago

Just make sure you wash your face still, otherwise they build up and cause problems

[-] hate2bme@lemmy.world 16 points 3 weeks ago

Because the fanfic would lead us further away from our path to god.
