I'd just like to say: Simpsons did it first. July 11, 1991, episode "Blood Feud", the last episode of season 2. The scene is around the 7 minute mark. The implication is that the blood transfusion has made him feel young again. There's actually a few references like this throughout the seasons of the simpsons. It's honestly weird to me this wasn't tried in the early days of performing blood transfusions. I mean hones…

"It's honestly weird to me this wasn't tried in the early days of performing blood transfusions." It's weird to me it wasn't tried the day after the first successful blood transfusion. A child would think of it. That's what's so stupefying...

If memory serves me it was tried, many times soon after blood transfusions become known to the public. Many rich in europe claimed the blood transfusions from the young rejuvenated them in many respects.

I do not remember where I read this any more 10+ years ago now.

Here is a small snippet I found with a few minutes of search that seems to be reference to the same behavior I remember reading about: https://books.google.com/books?id=bdIBlQXSKi8C&pg=PA78&dq=hi...

What a great plot for a sci-fi/noir novel; an evil old man captures babies and infuses their blood into himself. With a variant: the babies don't just vanish, they disappear for a while, and then come back. But alas, inexplicably, once they're back they begin to age very fast. Maybe they don't disappear at all, they just start to age and that's how the inquiry starts. People notice the disease and think it's some kin…

If the secret to immortality is baby blood, that's one of those hilariously cliche coincidences that makes me think we're living in a poorly written universe.

The inevitable "baby factory" scene in the movie is sure going to have some punch

As if I need another reason to kill babies. Perhaps there is some truth to gaining life energy by eating your opponents heart.

What benefits does parabiosis have over taking HGH? The effects of parabiosis in mice sounds almost exactly like the effects of growth hormone

That's what I was wondering... is it just the increased growth hormone levels in the young blood or is it the blood cells themselves? If I'm reading the article right, it was neither, but actually just the plasma: > Plasma alone had the same effects. “We didn't have to exchange the whole blood” Did they remove the growth hormones from the plasma? It doesn't say...

From some cursory wiki reading it seems blood plasma is quite the blanket term. Electrolytes, proteins, CO2 removal, it's involved in quite a number of places.

Am I the only one wondering what happens to the poor young mouse when it gets the old blood?

Starts talking about the good old days, complains about the noise teenager mice call music these days, nods off for a while then heads over to Luby's for an early dinner.

I am stupefied by this. Many, many times I have considered: "what would happen if I banked my own blood and transfused it back to myself 40 years later" And of course, my next thought was "of course that has been thought of, and tried, and the reason we don't all know about it is because it must not be helpful." But you're telling me that, in fact, nobody thought to try this ? It is 2014/2015 when someone got around…

There was a study done a couple of years back that showed that stored blood started to become less effective after about 21 days.

No, Simpsons wasn't first. See the movie "Being there" with Peter Sellers - the wealthy but aged and ill king-maker in this imagined U.S. gets regular blood infusions of 'young blood'.

Vampires did it first.
