Well said.
Lotta folks have broached the idea that their current house isn’t suitable for an e.g. infirm 85yo living alone. But since they (and spouse if applicable) aren’t in that condition, it’s fine to stay where they are.
I’ve told this story a few times, but I’ll trot it out again.
For almost 10 years I lived in a ~150 unit condo with mostly retirees. I intended that to become my retirement home too once I aged into retirement. Some folks were late 80s when I moved in, lots of vigorous late 60yos & early 70yos, plus a few like me in their mid 50s.
The facility was a midrise building with elevators. Each condo was 1-, 2-, or 3- bedrooms all on one level with included washer/dryer. Grocery stores, restaurants, parks, the beach, and recreation were all within walking or even power scootering distance. It really was the Big Easy Button as far as living arrangements. Which is why I/we picked it. During my time there I was active on the board of directors and was the president for about half that time. Which meant I knew pretty much everybody and everything that went on.
Now the punchline:
Over and over as president I got to deal with somebody who aged into enough mental or physical infirmity that they couldn’t live there successfully. Despite the ease, and surrounded by longtime friends and acquaintances. In some cases still with a similarly infirm spouse and in other cases as a surviving widow(er).
Beyond a certain age / degree of infirmity the logistics of downsizing even a 1500sf overstuffed 2BR apartment becomes overwhelming. Then the person is trapped there. Often descending into squalor, but always becoming isolated and unable to cope.
My takeaway was that to avoid the squalor trap we all need to reduce our life complexity before the need to do so is obvious. The folks who shrank their stuff and moved to a supportive elder community or in with kids or whatever did much better for longer than the folks who stayed in place, first voluntarily, then stubbornly, and finally because they had no choice. They were trapped whether they acknowledged that or not.
Those of us who have less local support via a strong extended family have more need, IMO, to do all that shrinkage and make all those moves extra-proactively. IME the nature of decline with age is slow and smooth, except for the sudden surprises of a stroke or severe fall or illness or accident. Then you’re stuck. Most folks also get lazier faster than they get incapable. But if you can’t summon the gumption to do it, then it doesn’t really matter whether you could still physically do it. You’re not going to.
IMO if right now the idea of moving seems impossibly daunting, you’re already trapped or nearly so. Note that “impossibly daunting” is not the same as “Eh, I like my space & stuff; I still use all of it. I could downsize / move if I had to, but I don’t want to now, and I don’t need to now.”
Take a darn hard look at your age, your health trajectory, examples of friends and family, etc. Do your best to avoid wishful thinking. We can hope for the best, but IMO it’s worthwhile to plan for something a lot closer to the worst.
But don’t wait, because Father Time is coming for each of us all too soon.
