When I run pre-retirement seminars one area we discuss is around where to live as we age.
People will often talk about retiring to the seaside, or into a city. They want a change.
The sea-side as it seems peaceful and they have good memories of summer holidays. One note of caution is to look at the place in the winter, it will have a different feel and you will want to see what activities still take place in these months.
Making friends is important to. It could be involvement with the church, or volunteering.
More people are moving to cities. You can walk more, there is plenty going on and when people have brought up children in family homes in a rural location it makes a great change.
