Diluting the blood plasma of older human beings rejuvenate them

> The idea a few years ago was basically that if you had taken an older person (or this works with animals too) and you basically just connect their bloodstream to the younger person, then the older person would be kind of, you know, quote ‘rejuvenated’ with the younger person’s blood to some extent.
> It was somewhat inconclusive, but of course, it really captured the imagination, just because of the bloody optics of the thing.
> But then there was this interesting study from a year ago that I think, or somewhere close to a year ago, that kind of really changed the narrative on this. It turns out that you don’t need young blood for this. Like, it turns out that if you just replace part of a person’s blood with, I think it was water and with saline, and albumin. Basically just water with a couple of other dumb things, then you can have basically all the same positive effects?
> It turns out that the gains from that procedure don’t come from younger people having good ingredients, they come from older people having damaged ingredients. And if you can flush those damaged ingredients out, then you can potentially reduce the level of damage in a person’s body.
> Once again, this is the sort of thing that’s still significantly too early to be really doing, but it’s the sort of thing that is definitely worth kind of doing more research and looking into more.
Seems a fairly extraordinary claim, requiring extraordinary evidence.
(Pilot study of only 8 people.)
