What other functions of real blood do you have in mind, that this doesn't at least have the potential to do well for a short period of time in emergencies?

Well, what about immune function? It's pretty interesting to have one when and after you're bleeding out...

And before you tell me the potential is there, please realize that we currently have only a very partial understanding of how that works, and it would certainly require at least two decades of science to get right.

I was asking, not arguing.

Ok, sorry
