This is about as far off topic of Defensive Carry as I think you can get. I started thinking aobut it after noticing a thread on a church's issue of safety, etc.
Does your church/synagogue/mosque initiate discussions about end of life care? I realize this is a very hard sell to anyone under 60 but certainly of urgent interest to those of us over 70. One of my medical school classmates just died at age 59 with ALS after being in a coma for many months. That is not the end I would have chosen for myself.
I have too often been in a situation of struggling to deal with families who have not spent any real time considering this issue. Mom is dying at home with some incurable disease and as she approaches the edge of the precipice, some one in the family calls 911 and rushes her to the hospital emergency department with lights and sirens going and places her in front of me. I feel duty bound at that time, in the abscence of firm written instructions by the patient, to do all the horrible things we do to try to stave off death for a short while. This usually turns out to be VERY difficult and uncomfortable for the patient and very hard on the family. Sometimes it is national news - like the Terry Schivo case in Florida that even involved President Bush and his brother.
You really also need to discuss it with your doctor and insure that he/she is on the same page with you. For example:
Physicians' religious leanings may influence treatment decisions.
The Los Angeles Times (8/25, Kaplan) "Booster Shots" blog reported that, according to a survey of 3,733 UK physicians detailed in the Journal of Medical Ethics, "the strength of a physician's feelings of faith can influence the types of treatment they offer to their patients." For example, "doctors with 'stronger religious faith' were less likely to talk with patients about treatment options that could shorten their lives, such as prescribing powerful pain medicines," and "less likely to keep patients in continuous deep sedation or to support legislation allowing doctor-assisted euthanasia." On the other hand, those "who described themselves as 'very or extremely non-religious'" were "almost twice as likely as religious doctors to report that they had pursued treatments that had the potential to hasten a patient's death, either intentionally or as a side effect."
Whatever choice you make, your doctor needs to understand that you are the one in charge of this decision...
If you are interested in resources for discussion with your family or for information for yourself, you can find some useful info here:

5 Wishes is another useful source and allows you to really tailor your own plan
If you are not interested in this topic you must believe that even though we are all mortal, God is going to make an exception in your case. Good luck with that...
