This has been well-known in the vampire community for centuries. [edit] More seriously, wow time to start talking about the ethics of immortality.

Please don't post substanceless one-liners here.

The second one sounds more serious, but "wow time to start talking about the ethics of immortality" doesn't engage with anything in this article; it's simply an immediate leap to something generic and obvious. That is not what HN discussions need.

How long would effects like this last? I mean, let's say a bunch of children donated blood for the cause, and we used it to replace the blood of a senior citizen.

I don't know how to phrase this properly, but how long does the blood maintain the youthful qualities? Do you constantly need new blood coming in from a young donor? Do you receive it once and you're good for a week? A year?

Isn't there a way to store your own bone marrow( or the cells that could make blood ) when you're young, and then generate your own blood in a laboratory.

Only one way to find out...

It seems like it would be relatively easy to test out. People donate blood all the time. I'm sure the effects are known of how much blood you can replace at once without causing issues. Without a doubt some elderly people would volunteer. Why can't we start giving them new blood once a week from donors, and see the results on their health or illnesses? I'm all for testing, but this seems like one of those things you could quickly move to human trials.

Only tangential to the ethics of immortality, more about possible consequences of immortality for a given individual is "All Men Are Mortal" by Simone de Beauvoir, highly recommended.

Should be done outside the normal blood donor system. There's not that much donor blood around, so it would be unethical to use it. Not a practical problem, but it would look and feel bad.

Anyway, yes, why not try this on humans? Sounds perfectly reasonable.
