The last card I filled out and signed was 2004. Actually, that's the only "blood card" I ever signed, as prior to that I only had the "Identity Card" for non-baptized people (which I still don't understand...why would they withhold the full protection of the blood card from unbaptized people if they want it?). I pulled it out and destroyed it about 2 days after my first post here.
After the changes to allow fractions, I could never wrap my head around the no blood thing. That, and I always instinctively push back when people try to get me to do something. So, I've never had a medical directive on file at the KH, I don't return the forms the secretary is always trying to get me to fill out with my address and phone numbers, etc. The blood thing was just another case of everyone saying it's important, but it didn't make sense to me so I refused to re-do it.
