This is completely unrelated, I know. But I will share that my family (my mother and her brothers particularly) have made the decision to allow my grandmother to starve when the time comes. She hs dementia in the advanced stages and will no longer eat. The alternative is a feeding tube and they have decided a feeding tube is something my grandmother would never want. They feel is compromises her dignity. Why did they make that difficult decision? Because she has been a prisoner over teh past decade of her body. Her mind is gone and her body continues to survive. She is aware of her surrounding and can communicate- but she has no mental function in terms of recognizing, knowing herself or others, etc. It is in its most advanced stages now.
So, in the coming year, she will litterally not be able to eat. She will be medicated so that her death will be peaceful and painless. But, yes, it will be essentially starvation. Sad, but she would never have wanted a feeding tube. I've seen it in her sister, and it was awful.

My grandmother is and was a strong and dignified woman. She would want the same for her death. Anything else, my mother believes, would be selfish and wrong.
