This is actually one of the mechanisms behind "blood swaps" done by the rich and weird. Donating blood frequently also reduces various accumulated "factors" that reduce kidney stress, encourage healthy new blood, and is overall beneficial to health.

Various other mechanisms can improve how effective your body is at recycling cells, encouraging autophagy and filtering things in the blood. There are a whole suite of various supplements and medicines that work in this system.

As undead, though, vampires no longer produce new living blood, so require fresh blood of the living to restore lost function. Or something.

I guess that'd make Bryan Johnson the ultimate thrall?

The replication process makes worse and worse copies over time. Plus the cleanup crew gets confused and weak. Each bit of aging makes the process of keeping you young work less well, and hence you age more + faster.

Who knew we could coexist with vampires if we give each some kind of dialysis machine? Imagine the kind of cultural works someone with centuries of experience could create. Imagine a vampire historian!

Not the same blood, but dead cell matter does accumulate in plasma over time. The body has active mechanisms that perform cleaning: https://pmc.ncbi.nlm.nih.gov/articles/PMC7392086/

Or indeed daylight

I was going to suggest some other vampire remedies, but I was worried Palantir will scan this and tell ICE.

> I don't think this [ed:periodical dilution] makes sense. Our bodies do not use the same blood forever.

You might want to read up on chaperone-mediated autophagy, and how that declines over time. There's a point to be made that yes, in old age we collect things in our blood that don't belong.

It might not be solvable through dilution, but it's not like we get a full blood change every 5K miles either.

Maybe garlic alludes to the working class.

Imagine showing up to a meeting with Thiel wearing a huge garlic and onion necklace.
