Didn't the exact same team who first discovered this later realize that they had similar (if not better) effects by simply diluting the subject(=mice)'s blood with a saline/albumin mixture? If I recall correctly it was simply a matter of removing a buildup of waste in the blood that the body had lost the ability to remove itself.

Yes, more recent work indicates that just replacing the old blood plasma is enough to show the effect. See:

(kudos to this journal for not being behind a paywall!)

So, as you suggest, it now appears to be more a matter of "bad stuff" being in old blood rather than "good stuff" being in young blood. Apparently there is bad stuff that the kidneys, liver, etc. just cannot remove from the bloodstream, and this bad stuff builds up over time.

I suppose one analogy might be that no matter how good your oil filter is, your car still needs an oil change once in a while.

So frequent plasma donations would be a better approach for these billionaires. It’s just such a difficult/uncomfortable/time consuming process.

There is no way I can separate this research from 'The Blood Boy' episode of Silicon Valley.

Nice, I can't wait to see billionaires live longer by paying for blood from babies. (only half sarcastic)

One could simply donate blood often and have the body generate new red blood cells.

Blood for the Blood Gods isn't exactly new news, isn't it?

So the really interesting question is, why does newsweek.com revive old news this week?

Do they need fresh blood?

Wow. This was straight out of the Silicon Valley TV series.

It was based on real research. I didn't see conclusive results confirmed though. Thiel is really into all of this afaik, which I actually applaud him for.

Silicon Valley did that as a satire of Peter Thiel in the first place.

I had read somewhere once this is where the concept for vampire like demons in folklore came from. That at some point in history drinking the blood of the young kept you youthful longer.

So, I guess we're one step closer to a world where we're ruled by immortal billionaire elites who harvest the blood of the underclass to sustain them??

Boy... QAnon is gonna love this.

We've known about adrenochrome etc...
