In my case, I am hoping to manage my own cognitive impairment / dementia progression. I have a dear friend who is also a hospice nurse and I have legally designated her to be my healthcare power of attorney.

When it is time to park me somewhere, her job is to find the nursing home with the worst pneumonia occurrence rate in the state and put me there with treatment restrictions she will communicate ad hoc that only allow me to be treated for pain and anxiety - but specifically not to resolve any disease or condition which might extend my life. So for instance, no antibiotics. And I will have a DNR.
In short, If God sends me an ability to exit somewhat gracefully, I want to have no obstacles placed there by well intentioned facility staff or physicians.

But thats me. I just want to relieve my children of that burden. They all understand my intention and support it.

Short of moving to a country with compassionate end of life options, this is the best I can manage.
