Don't avoid your will
I've spent the day in a semi-modern hospital in what seems like my father-in-law’s last days. Communication is barely possible. Some yes’s and no’s come through, but maybe not for long. He left some signed notes from his past self about not wanting to live off feeding tubes. But there are all sorts of decisions (ie: who does he want visiting or not?) that he can’t communicate because he’s too weak to speak. People don’t like writing, let alone writing about the ideal conditions for their death, but considering it must be the most disorienting and climactic of experiences, it could be worth doing a lot of writing to help you and your caretakers in the future.
