I have moved both here and abroad about 19 times, nothing to do with the services and as an adult for work reasons. I have driven all over and am happy driving, so that I spent 10 years doing hospital car service as a volunteer, three days a week when I retired 'and this was mostly in rural North Yorkshire, so long distances.
Have always thought things through carefully and while I loved gardening and in my last house had a garden on three levels, but my independance matters most to me, above everything else. As a widow, I made a list of my requirements, from ground floor accommodation, nearness to trains and buses, if I could no longer drive. Availability of doctors and hospital etc. Then I also looked for a quiet area with two different ways to get out, and then was able to spend time looking for the most suitable place and helped by knowing the area, from the volunteering.
I have ended up with a ground floor flat , in a quiet cul de sac which then has two different roads to come out onto, and at the moment I am still happily driving around but should I no longer be able to do so have the public transport. I miss my garden of course, but with various health concerns this has been a good move, which has allowed me to remain totally independant as I hope to be for the rest of my life Being able to make your own choice , and looking ahead , seems to me to be important. If you have to cope with ill health or other problems then ending up somewhere you dont want to be makes it all 10 times worse. Whilst you may consider where your children live, if they are of working age, you will not be sure that they will not move at a later stage and so I think it is important to look for a place that appeals to you, not just to be near family.
