do it if you can find happiness, but consider that the amenities you need, if you don;t drive, you will be reliant on local buses, often a big drawback,
doctors, hospitals not in the location you go to, but a bus ride of two away, that is if they run, an area that some family live in have poor public transport, so they need a car to get around. Its a nice thought living out in the sticks, no one to bother you, but that can also be a double edged sword.
someone within easy reach of London, perhaps Essex, but you will still be reliant on trains, and bus to get to the station. Perhaps do a recce to a
village, or see if any friends who live outside the capital can put you up for a few days to see how you get on, it will give you a taster of how life could be, it's worth a try.
