I have the same clause in my living will. If I'm that close to the end, I don't want even the basics except as necessary for my comfort (like water with which to take pills, assuming I can swallow).

It has surprised me on two occasions, my grandfather and my great aunt, how slow a process death can be. I rather hope my own end will come more quickly and in the middle of the night--a sudden, deadly stroke at the age of 115--so I don't linger. Or draw spectators.

Thanks for the update, Geonagual!
