When Mother (94, Aricept 10 yrs, 21-23 on MMSE) heard that her twin sister had died suddenly, she said "Wasn't K. lucky, she'd have hated to be an invalid". So even though, I think, she doesn't know about the horrible future possibilities of Alzheimer's, she's all in favour of a rapid exit (she found my father dead on the floor one morning, and is very positive about that too: "He'd have hated to be an invalid".)
She's actually the only person involved who doesn't know that her sister took her own life: left a note saying that: she'd lived long enough, her shakiness from Parkinsons wasn't going to get any better, mobility was getting more of a problem, and she hated the idea of ever having to leave her own little house (lived alone, spinster) and perhaps be in a home for years. A very well-organised lady who kept in control of her own life right to the end (and had no signs of any dementia). (It was a pity that the Coroner's Office aand the Police, between them, then managed to sit on all the paperwork my aunt had carefully set out for us, like the list of who to notify, until after the funeral... but, thank heavens, no serious harm done and all the people she named were there at the funeral.)
I'm hoping that Mother is as lucky as Father, to go out like a light while still living an active life. Well, no, she's already nothing like as active as he was, but at least she's physically quite healthy and still getting pleasure from a lot of things. But something swift, so she never has to go into hospital, please. Pam
