I agree with you, and formed my opinions after watching 2 specific instances.
In the first, my father had a stroke and was in a "vegetative state". The Dr asked if I wanted to feed him, and when I said yes he argued with me. "He could live like that for 20 years.""He will never get better".... etc etc. I told him when God wanted him home the Dr wouldn't be able to keep him here. Dad woke up 10 days later and we had the best 2 years of our lives after that.
The second also involved a stroke. Mr G was at a hospital and overhearing the conversation of the relatives of the stroke victim. They were asked if he had a living will and when told he did the medical personnell took him to a different room, removed all life sustaining support, and let them sit with him to die. No one explained he could recover, or that perhaps the ventilator was a temporary measure of support (like with my father), or that these drugs will reduce swelling (they removed IVs)and on and on. They just removed him to a room to die. It was freakily cold blooded.
Mr G and I say be heroic. If we are ready to go, God will take us.
Did the doctor have anything to say after your Dad woke up?
