Oh great, now I have to worry about DuPont and Dow coming to repo my blood.

Welp, better make an appt with the leech doctor then

Not OP, but apparently they're useful for when you want a continuous, slow drain of blood. The ones they breed for hospitals don't carry disease, so you can just kinda plonk it onto the spot that you want blood out of, and replace it when it gets full

Wait until you find out what they still use maggots for...

It's less about the blood they suck out and more about their saliva. It's a natural anticoagulant.

Amputation sites I think? The suction attracts blood flow to the area and supports healing/retention of blood vessels... I think. Neither one of us clearly can be bothered googling but that's what I recall...

For skin grafts after burns; the leeches' saliva has anticoagulants that helps blood flow through the microvasculature (tiny blood vessels) of the area. This helps promote growth of new blood vessels, as well as improve the health of the current blood vessels in the area.

TLDR: Helps tiny blood vessels in skin grafts (and other procedures), reduces failure of said skin grafts

Donate 100% of blood, then fast. You'll be microplastic free for the rest of your life!

I don't think any filtering happens in dialysis, unwanted stuff just diffuses to another solution

Yeah buts it's fresh micro plastic and not this stall stuff I've had in me for years.

That should depend on how the chemicals accumulate though. If all the plastic ends up in your blood and never gets naturally filtered out, it could make sense. Maybe it builds up in your fat/muscles instead though, or gets filtered over time and the amount in your system is the same as the amount in what you have recently eaten, idk

Somehow I don't think they'd mind too much, provided you give them a nice leech habitat.

Until Socraleech comes along and they force him to suck hemlock.

And 4Chan, which is the worst form of internet advice.

We have some very limited ideas from correlation and limited lab testing that allows us to say easy things like putting junk in vital veins is bad (the nature article) but that's only a fraction of the types of microplastic and possible interactions - we know almost nothing about most of what's happening.

And to be clear I said they might be good for us as hyperbole, it's of course possible but what's far more likely is a myriad of long lasting health effects causing serious damage in obscure and complex ways.

In a century they might be saying 'those plastic brain gen alpha caused so many problems' just as how it's common to hear people talk about lead brain boomers... or maybe 'wow crazy micro plastic gave us superpowers, that was lucky'
