Thanks for the scans on these cards, Blondie. I really think this will be the next step in the evolution of the blood policy. Witnesses already can reinfuse their own blood as long as it is attached to the person. It can be reinfused up to a few hours after surgery. Looks exactly like a blood transfusion.
Next step is to store your own blood away from the body. They already use stored blood from others for their fractions, so it is not that big of a jump.
If they actually sent these out, they must be close. Maybe they just need an old timer or two to die off?
