Side note: Speaking as a male blood donor, donating blood has benefits for the donor as well. Particularly because we're not regularly performing blood regeneration, there's a number of benefits related to it. And that pint is fresh, new stuff. :)

Feces are brown because they're full of expired blood cells (according to high school physiology class). So I think we're renewing it all the time.

We are continually performing blood generation. What on earth are you referring to?

Ah, I had larger than average/sudden blood loss in mind. My bad.

I'm not a biochemist, but my understanding was that the natural, far slower rate at which blood is broken down / discarded is much less conducive to having a good supply of healthy Erythrocytes than what you get when half a litre of blood must be replenished. Upon doing a donation that's a solid supply of fresh red blood cells into your system.

I was referring to it specifically being beneficial to men because they/we do not have menstrual cycle - where blood is refreshed at a higher than average rate as such.

Also. In case of a trauma, it would stand to certain reason that someone who is a regular donor would be better equipped to recover from this than someone who's never experienced blood loss before.

This is not going to end well. Human trafficking is already a seriously bad condition in most societies - with this kind of science, I doubt that the black/grey markets are going to ignore the fact that there are very, very wealthy people out there, willing to pay for a little youth or two. This really speaks to the ethics of science, and technological morality. The world simply isn't ready for some of these major ad…

Come on. Let's start with a positive comment. (I think this is one cause of our technological stagnation. Every article about a new technology has a comment like this at the top.)

Sure, lets just start with the positive vibes, overlook the potential ramifications for the creation of a real vampire-class of humanity, and just enjoy the fact that the old can exploit the young and become strong again.

I mean, whats wrong with that, really?

Here's the thing .. we live in a dangerous world precisely because technologists decided to ignore the social ramifications of their work and only focus on 'the positive' that comes from it.

I mean, the Nazi's and Imperial Japanese did a lot of positive things for human sciences .. can't we just enjoy the fact that their research into the limits of human endurance has made it possible to be a better military pilot? C'mon people ..

Go on?

Ah, thanks, I elaborated a couple of posts above - https://news.ycombinator.com/item?id=14760815

Earlier quoted context omitted.

Western world is already struggling to find enough blood donor, and one of their main source are the students. You would not want to force those students to have to choose between morality and 1 order of magnitude more money than what they can do in the official public blood donation center.

It is not immoral to sell one's own blood, so long as one is not left unable to fulfill other moral obligations.

The moral bit is choosing between 2 competing blood donations service - one that is run publicly to save life, the other to extend the life of healthy individual. I make the assumption that the remuneration of the second one will be most likely way bigger than in the first case. The only reason people would chose to donate to the first one is morality which is unfair.

The morality of the remuneration is orthogonal. I assumed we were talking about countries where it is moral and legal to remunerate blood donation. I don't think that countries that today do not allow remuneration (for any reason) would allow it for this new use case.
