I think it is true that there comes a time when we wonder if "this is it". Usually after retirement we have a few years of really enjoying the freedom it brings but then, there are signs of aging in ourselves and our friends and it seems like it is downhill all the way. The chat with old friends and neighbours seems to be about illnesses and medication and I can understand the desire for a new start. Like "Gagagran" I am not a adventurous person and the thought of moving somewhere new is too scary!
But I DO understand.
"Maisiegreen" I would say again though, give the East Neuk of Fife a three month try (in the winter) if you really fancy it. Only then can you be sure it is the right place for you. It is idyllic for tourists but not sure about incomers.
