Bad blood is better than no blood!

Also, I'm not certain how much they treat blood, but I wouldn't be surprised if it ends up being a purification system sort of similar to Dialysis where you rely on an external machine for removing impurities.

That's a gross mischaracterization because anyone who is donating blood regularly as a discipline is likely to have blood that is substantially better (rather than worse) than average. Those with poor health practices will typically simply stop donating as they will lack the discipline to continue.

Fwiw, it is the responsibility of the blood banks to do due diligence testing.

> does this imply that you're just giving shitty blood...

2 questions: is there any other kind? If there were, ate people requiring transfusion in a position to make demands to the donors (not vendors)

That's more nuanced. The alternative is they get no blood and die.

If the blood don't contains long term detrimental pathogen, that's seems like an okayish tradeoff.

The microplastic filled blood will manage to oxygenate their brain and other organs and save their life, and then they can donate it on to the next person in need.

Feels a little homeopathy... How many people can we put the same blood through?
