I can’t answer your question but… a few years ago I remember a story where there was an elderly lady who spent all her time on cruise ships as it turned out to be no more expensive than going to a care home and had a similar level of services. (I think this was either the UK or Canada but don’t quote me on that.)

In my country it’s free to get a nurse visiting you twice a day when you’re disabled (including old age related disability). You’d also get massive financial aid for a live-in person, but they’d normally be a family member who would get a government salary + possible adaptations to their normal job (eg always working from home).

Hospice is a last resort and it’s incredibly expensive.

This really depends on the country you live in.
