We moved about 4 years ago, just before DH2s 70th birthday. I had threatened to leave him if we hadn't moved by then... 
We lived in a 5 bed house with 2 acres of land. The garden was getting too much, there was only one bus a week apart from that.
Having seen too many wrinklies pushed into moving house, I was determined to move at my own terms, when we were young enough to settle in and make friends, or at least links with our new house.
we are now very happy - a move is always extremely painful. We live on the outskirts of a delightful medieval town in SE England. Once DH has stopped mourning his garden, he is happy and well settled in. We have bus, train and taxis within 5 minutes walk, ditto small supermarket, doctor, dentist and other facilities.
We have never regretted our move, though I cried lakes over the things I had to get rid of/sell/give to charities. One had to be adaptable.
Go for it, Stainedglass. Go while you are still adaptable; you don't know what life will throw at you later...
