Below is a link to an interesting discussion on a finance/investment related forum related to being a solo ager:
CCRC's are out. Tips for "aging in place"? - Bogleheads.org
I'm not expecting any magic answers or solutions, but it would be interesting to hear from people who are actually experiencing this now--or planning for it in the not-too-distant future--how they're doing it and/or what their plans are.
I've got some younger cousins who theoretically might help help me out, but that's a HUGE ask, and for me at least, not a great plan.
