Here in the lower midwest, I haven't heard a peep about it. I don't have my card filled out, and don't care to, but no elder that I know of has done anything along the lines of getting compliance about it.
I know one things for sure, if it came down to it, live or die, I choose to live. Now if that means a blood transfusion then so be it. They can go ahead and DF me if they want. "I'll live with that." Pun intended. :)
