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

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 kind of virus; but a young journalist trying to connect the dots notices all affected babies stayed at the same clinic at some point.

He goes there to see for himself and is greeted by a brilliant doctor who's wise beyond his years...

The future of Silicon Valley: "This internship really sucks. Just when I think there's nothing left they can ask of me..."

See, hipster bros are good for something after all.

I transfused this blood before it was cool...

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…

Transfusions seem unlikely to work at this point based on evidence to date, probably because the factors involved are very short-lived. E.g. transfusions failed to move the needle in mice: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4215333/ There is a human trial for transfusion of young blood to Alzheimer's patients but this is probably not going to tell us much, because it is so specific, and because the mouse tra…

Well the Alzheimer's study is still useful in its own right.

You don't need a transfusion to do this. You just need to work on your blood health.

Excerpt:

“I thought, 'Hey wait, they're sharing blood,'” says Michael. “'This could answer that question we've been asking for years.'” At the end of the presentation, he ran up to Irina and Rando. He had not even finished his pitch before Rando said: “Let's do it.”

It was when I read up on how the body reacts to high altitude that I had my aha! moment that the blood was the common denominator between the gut and lung issues in people with CF. When you go up in altitude, you pee more. Well before you see altitude sickness, the body starts dumping wastes via the kidneys that it can't breathe out due to thin air.

The leaders of the Chinese communist party have already found this long time ago. As I known the old leaders of the chinese communist party change their blood of PLA periodical to keep them health. one article could find here: http://app.secretchina.com/node/472395 (in Chinese)

It looks like hieroglyphs to me.

Here's google's translation: http://translate.google.com/translate?hl=en&sl=zh-CN&u=http:....

Surprisingly readable after you get few paragraphs in and start picking up on the common mistranslated words (Some other title for Mao is being translated as "hair").

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 honestly the study wouldn't even be ethically questionable. You find patients that need routine blood transfusions and track their health over a period of time, you then administer blood transfusions from sources where you can control for the age of the blood donor.

I wouldn't be surprised if it was never even thought of because people seem all too willing to think of the body as "just a machine".

Given that we literally urinate out neurotransmitters, and that young people tend to be happier (it's actually called the happiness U-bend, in that 18-21 year olds are as happy as 70 year olds, and 50 years old is the lowest point in peoples reported happiness) so we could just be shooting people full of--quite literally--happiness. Given that severe depression can lead to myocardial infraction, I don't doubt general depression also has long term health effects. Also I don't think antidepressants would benefit, just because they generally make people "not feel" rather than "happy".
