We've learned a lot about hospice care lately. When people are failing with little to no hope of not failing further, in the US you can get hospice care. It's through Medicare which, when you think about it, you are indirectly paying for and for which the person in question already has probably already done.
All it takes is a note from the doctor, and the "health proxy" agreement in which you agree that no further aggressive medical treatment makes sense for the person in question - or for yourself...
Yes, paying for hospice is cheaper for Medicare than paying for costly, hopeless treatments.
We had been mistaken in thinking that hospice was only for people with terminal cancer, and the like. Nope. Bad Alzheimers, sure, but also for any hopeless situation. The hospice teams seem to be excellent, and even includes religious support. Yes, they can give you some morphine for comfort too.
We all have to go sometime. It shouldn't have to be a tortured, hospitalized ending. I'm not ready yet although I did joke with Mrs. BD about it during my food-poisoning ordeal. She knows that I will want the morphine and to float away into the stars.
