final, next chapter with my mother:
One visit to the nursing home (alzheimer's care), I suspected they were feeding my mother a lot of food. She overall was bedridden for 5 years and down to 90 pounds or so. Why does a totally inactive 90-pound woman need so much food, I asked my self?
Had a meeting with several of the staff, told them that my mother's will said she was not to be kept alive by artificial means, and the 3000 calories/day was "articificial", and thereby violated my mother's will.
They said she was so deteriorated and incapable of processing protein that they had to overfeed her to provide enough protein (iow, keep that $3000+/month bed occupied). Ice cream and cake and LOTS of protein.
I lost that battle because my sister had power of attorney/guardianship and thought letting our mother die a natural death was inappropriate or cruel whatever.
Finally, after burning through $250K+ of her savings and liquidating her house, for 5 years of Alzheimer's care, my mother died.
afterword: funeral home charged $800/night for two nights to keep my mother's body in a refrigerated drawer until the burial. They also offered me the option of burying my mother so I could share the same grave, next to my father. That gem was, IIRC, about $3K. No thanks. Sunset Funeral Home/Cemetery, Austin Highway.
