My two cents: you’re very young and I would be surprised to hear of anyone your age thinking it was something to do soon-ish!
My other two cents: it is easier to think about it in advance and scope out what some different options could be several/many years before you might need it. Depending on health that might mean when you’re 75 you look around and think about options, and if moving to a community may be one of them. And if that is the case, to visit different communities, and consider what that entails, and to put your name on a waitlist for the future.
Every family that I’ve known that didn’t think about it in advance has had great stress and worse outcomes when they’ve waited until “something happened” and then were forced to move abruptly into a place that they never would have chosen if they’d had the opportunity to choose, but it was the only place that had openings that you could move in to right away.
When it is an immediate need situation, those are typically due to an accident, a fall, a stroke or other debilitating medical event, or the death of one spouse who was providing additional care. People that move to communities under those circumstances tend to not have the ability to join the community: they are quite ill, immobilized, grieving, or all of the above. And that greatly affects their mental and physical health and they can decline rapidly.
We have family friends in which one of their parents was having memory issues and their spouse was shouldering an increasing load in ways that crept up gradually and seemed doable. One day that person tripped, fell, and did not recover, and it became immediately apparent that the parent with some memory issues could not live safely alone. And so an extremely rushed placement was made (during a time of devastating grief) to a facility that they never would have chosen amongst the many options in the city, because all of the wonderful non-profit communities have waiting lists of 1-3 years. It was brutal for everyone in their family.
I mentioned up thread that one of my parents can’t live independently, and my parents moved earlier than they truly “needed” to. The most significant reason was so that both parents could really join the community and build a life there, and that if/when something happens to the spouse that cares for the other, that the surviving spouse would be surrounded by friends and supports and there would not be an abrupt and terrible transition; they’d continue living in their home.
There are also other options! And that may include living in a home that is fully accessible if one were to need to use a wheelchair for a few weeks or a few years. And in which different types of supplemental care could be arranged. It’s useful to see what those options could be far before you actually need them, and when you feel comfortable evaluating all the different choices.
But you’re only 65 and 69! And that’s a question I would think is for down the line
