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. :)

Blood donor as in you donate to blood banks for use in hospitals or as in blood boy?

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…

I wouldn't be quite so worried. If the effects truly do end up being due to soluble signalling factors in the younger blood (and not immune cell implantation or some other physiologic quirk of the cross-wired parabiosis experimental setup that won't transfer to non-inbred humans) then those factors will be synthesized in bioreactors and made into a synthetic plasma product - that's also the only likely way to make money on this for a therapeutic company.

Earlier quoted context omitted.

Is there any research that confirms this. I ask because I hear it everywhere. But it feels too convineant an excuse to make people give blood :) (voluntarity in most cases)

I've always wondered if it's a viable wight loss technique. There must be a certain amount of energy that goes into blood production. And losing wight by sitting still for a while is the holy grail. Market it right and the billionaires might even be able to charge us to give them blood.

There's a 650 calorie/pint figure cited on many, many sites, but I can't find the original source for it.

Some sites claim it comes from the Mayo Clinic, others list the source as the University of California San Diego, and so on

that is until the market is opened up and regulated. with so many young people around realizing that a thing they constantly produce for free is worth something - there will be no incentive to go through the criminal path. also worth mentioning that this could positively impact young population health as there is now clear monetary incentive to keep your blood healthy. it's a win all around, regulators just have to b…

Blood is worth a lot, people know that already, and illegal blood farming exists in some countries.

But paying for blood increases the risk of people lying about the quality of their blood, which is why the administration doesn't incentivize blood donations.

Your argument about criminality is very wrong. Maybe I speak for myself, but I'd much rather be a criminal than a professional blood donor. People are not criminals because they have no other way...

Perhaps UberEats can pivot to UberBlood? Fresh young blood of the right type on demand via app. Blood boys can be regular Uber drivers when blood demand is low. You're welcome Uber.

But for UberBlood it will be $3/h instead of $2/h?

> risk of people lying about the quality of their blood

this is where middlemen companies come into play, testing the blood and ensuring level of quality

> People are not criminals because they have no other way

sorry, i was not clear enough in my comment. what i meant is that opening up the legal way to sell blood reduces the incentive for criminals to do blood farming or human trafficking for the same purpose. much like legalizing marijuana will push drug traffickers out of the market.

I wonder if we also age faster while doing this. Assuming cells go dormant after dividing a number of times, won't this repeated regeneration have a deliterious effect on them.
