I lived in the EU (Menorca, then two different moves in France) ....could have stayed in France after my husband died but to be honest although I was told I would be ok to qualify for their rigorous system in applying to stay, I simply couldn't be bothered !!!! so I moved back to the UK ...where we lived in France was extremely rural, and although I was used to having to drive everywhere, I figured there might come a time when I no longer could .....although at present the licence in France is for life, whereas here it is 70, after which you need to apply again ! and I witnessed other English widows who had never learned to drive, and it was extremely difficult ...taxi to the local (10km being the nearest !) shop were then around 35 - 40 Euros each way ! so even if I had decided to stay, I would have had to move into a less rural environment ......have to say I love it here ..I chose to move into a retirement flat 15 minutes from a big city ...I have everything ..airport, ferry, theatres, cinemas, a huge concert hall, loads of clubs and things to join or volunteer in ..I moved to the coast which is just lovely ....go for lovely long walks in the countryside (hardly walked anywhere when I had my car !) ....so as long as my health lasts I am going travelling on cruises, holidays, etc etc and when I have to stop, I can just look back on it ! SO if I WERE going to move back to either country, I would (I am 76) definitely chose somewhere less rural, with a good transport system, Drs, hospitals, a rail station et ...Menorca has none of these, and it can be quite lonely in winter ...there are some good walks, but little else ! France, yes...loved living there, but again, nowhere rural ...it is sad, but there comes a time when you have to think long term ..............have you visited any of the countries you are thinking about ? if not, then go for a few weeks at a time (not forgetting the restriction on how long you can stay out of the UK) and then decide ! good luck
