@Curious Me I called the Hospice center here a few weeks ago. If my husband gets sick, he isn't going to get a test, or go to the hospital. He is over age 80, and not in the best health.
The pallative care nurse told me that they would give him morphine if he was struggling to breathe. He doesn't have to go to the hospital or anything.
So, we know what the plan is for him. Hopefully not needed. But I already filled out the paperwork needed with them. All I have to do is call.
I'm basically in the same boat as your husband, old and not in the best of health. However, I will go down fighting and enjoy my life before anything bad happens. My ex-hubby was on palliative care, out of it until he died. I told everyone I will not go that way.
There are plenty of things a body can do without going out and putting themselves in danger - read a book, get a rescue dog, eat great meals, watch movies, learn to knit, sit out in the sun - read the Bible and put your trust in God.
