I lived for a while in Norfolk, it is so cold in Winter. Going back on holiday I see that in some of the lovely little towns facilities are closing, banks, there are fewér buses, and the main hospitals are kings Lynn, norwich and Yarmouth. Well to do people are pushing up house prices too. If you're too near the coast in places there is a lot if erosion. I think you really need to be near a good railway line so Norwich or roundabout there would be good
My children don't want me to move far away, so if in the future I have problems they don't have to spend a lot of time travelling to help me, one lives about an hour and a half away, the other about 29 mins away, and I can get into London easily. V tempted to move back to York's, when my parents were Ill the medical and social care was so much better than it is here. I'd be a long way away from my children though. Someone suggested Skipton, it is surprisingly ac feasible, Ilkley too, or even Parts of Shipley, public transport is good and there is a lot going on and you are very near lovely countryside, and a v shirt trip to Leeds in the train.
