The article misses the simplest technique:

Just donate blood as often as possible. This results in a loss of cholesterol, other bad lipoproteins, excess iron in those who have it, and PFAS toxins. It is frequency-dependently associated with longevity.

Whole blood donation avoids the plastic lining of plasma donations, with the latter undesirably transferring unwanted microplastics into the body.

For those with sufficient spare money, instead of donating blood, just get various blood tests every other week, additively comparable to a donation if the tests are substantial.

Granted, this is antithetical to being a vampire, but you will still have to make up for it by supplementing sufficient healthy nutrients, e.g. electrolytes, ferric pyrophosphate, protein, etc. to allow your body to quickly restore the lost blood.

As a disclaimer, do not ever donate blood if you use narcotics, disallowed drugs, injectable drugs, or have unsafe intimate practices, or might have chagas or TB or even long Covid.

>It is frequency-dependently associated with longevity.

Paper where more frequent cycles in women correlate to longer lifetimes? That would have to be true if this were true.

I'm assuming you're referring to blood loss from menstruation? That's typically only 30-40 mL (1-1.5 fluid ounces, about a shot glass).

Nowhere close to the amount given during a donation.

Heavy bleeders would be in the 100-200ml range. This group should correlate with longevity.

So maybe they were on to something with leeches?

Every time I do blood work I almost faint.

I used to have this problem until I was given the tip to tense various muscles throughout my body during the process. Do not listen to the nurses who tell you to relax!

Is there any evidence?

does this imply that you're just giving shitty blood to people that need life saving procedures?

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.

> 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)

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?
