BK...... Actually no I never discussed any of this with a doctor.
No need to do so. My family is very Catholic, I was taught from a very early age that we need not invoke extraordinary means to save a life. I watched as the medical and clergy in my family decided what should be done. Add to that 40 years in hospitals and I know what I want.

On a general note I try to not live in fear...I take things at face value. To me this regulation is a good thing because it gets the discussion going on these issues. Trust me you will not be in control at the end .... sometimes even if these papers are available. I have seen it....

Still your concern should be addressed....
