George, Sorry about your Mom. I can explain this very easily; Some people simply do not want to be handled or "managed" Thats one reason that I stay as far away as possible from the modern medical establishment,. Far too many Doctors see death as a "failure" on their part. I dont know if its simply their fear of, liability,,. or that they simply missed that day in Med school where they explained that death happens to everyone,. Yeah, some folks at some point simply get tired of living for one reason or another, while other will fight to the very end to hang in there. But that should ALWAYS remain the choice of the individual, not a Doctor,.
