For us, it has been a total of 22
full moves before retirement.
BUT...
Here's an opinion about retirement living.
The country, state, town, or even the climate doesn't matter as much as finding a lifestyle where you are comfortable with the people with whom you may spend much of the rest of your life.
So, while not being 24/7 socialites, we have found that being in a "COMMUNITY" is not like living in a town. Instead of living in a economically, culturally, and age diverse neighborhood, with workers, and families and kids, our choice has been to live among people with whom we have common interests and goals. The rest of life, takes care of itself.
In the pre-retirement years, we live in neighborhoods, or perhaps rural areas, but we typically live our lives with 5 days of necessary activities, and two days "off". After retirement, it's 7 days continuous of whatever you choose.
Instead of having to hunt out friends or a social life apart from your own home, IF you live in a COMMUNITY of "like interested" people, you naturally merge into a society where you will be comfortable.
My guess is that the reason retirees don't do this, is because they have never experienced (for want of a better word).. communal living. It's an experience that has to happen... as it defies explanation. In a vacation area, experiencing this, is a matter of renting for a month or two... since being taken around by a realtor to see "houses"... is a shallow means of making a decision. Seeing people in action... meeting face to face... knowing what happens on a daily basis in the "community" is more of a measure, than a slick brochure, or an hour guided tour.
The second part of the decision, is really KNOWING what you want. When we moved into our community, the last thing in my bucket list was dancing, and parties... We ended up loving Square Dancing.. (back in the 1990's)... and this turned to line dancing and ballroom dancing later on.... Can hardly believe it myself!... Then another surprise... putting on and Emceeing parties... From a guy who spent much of his life reading books. Then an easy transition to canoeing and biking, body surfing (Florida), Billiards, and teaching computers.
All of this and more, because of living in a community. From being somewhat asocial to knowing every one of the 350 residents and their dogs.
We didn't start out that way... and even now, many of our neighbors are less active and indulge in their own interests... Still we all have common bonds. Similar age, similar socioeconomic backgrounds(middle income), no on-site kids, and the same outlook on life that brought us all together in the first place.
Now we live(d) in three different retirement communities and find them all to have the same basic characteristics... Our current, and probably final residence is in an older, less active community, but with the same kinds of people who have the common goal of enjoying the retirement years.
My opinion only...
