Maybe they don’t do it anymore, but during the 1980s after you gave blood they gave you two secret stickers. If you put one on it, it meant it could be used, but the other meant that it should be discarded. By the time I was in grad school I’d given three and a half gallons of blood, but that was the final straw for me.
I hate to say this, but I am really against the hypocrisy of confirming the blood bag after I’d already donated it. This practice came out of the AIDS years, which admittedly never went away, but I couldn’t stand giving blood after that,
The reason I remember it so vividly is that the original came out several weeks after the invasion of Ukraine, and I thought it was meant to represent a battlefield.
