Not all nursing homes are torture chambers, my sister who is 91 is reasonably happy in hers. She hated it at first (November last year) and complained that there were some people who were 'off with the fairies' most of the day but she hunted down three other women to play bridge with and they get together twice a week. Fiercely independent, and a very fussy eater, she actually said the food's 'not too bad', so she's slowly coming around. I might mention that it's a Catholic-run home, even though she isn't one. She paid a deposit of $100,000 up front but not sure if it is refundable or any other monetary arrangements.
If we should get dementia as we age, our loved ones will eventually have to put us into care because there is no other choice. And we won't care, because we won't know what's happening.
