I’d be worried about not really being able to make my own decisions and not having someone there to help me out.
I don’t know about you, but I sure hope I’d be able to check out before that time comes for me. Before my mind and body becomes too feeble, I’d like to be able to just nope out.
I don’t use a shower, rather, I have a bucket (or two) of water and a dipper. I can ruminate and think about things while giving myself a thorough scrubbing, and not consume any water.
I can take as much time as I need (much to the irritation of people I live with) without consuming any more water.
