Yeah, I remember the lecture we got a few years back about calling them "no-blood" cards or medical directives. Not that that changed anything in the witness vernucular, of course :)
But what about actual blood cards? I had to sign a medical release the other day, and as I was writing down my mother's name as emergency contact I thought to myself, what if blood becomes an issue? Based on my new understanding, I couldn't care less if I got a blood transfusion - in fact, if I were in need of one, the last thing I would want would be for my still-witness relatives to refuse one for me if I were unable to speak for myself.
So maybe I should make up a card to carry in my wallet: "Please do not let my witness relatives deny me blood based on their well-meaning convictions" and include, say, my blood type and other vital information. Just in case, ahem, they face a "faith challenging situation"...
What do you think?
