My wife and I carefully considered where we wanted to retire to. We'd both seen elderly parents get gradually cut off from the outside world. For her parents, we could do internet shopping remotely for them which worked. But my father would not have that, so when he gave up driving he was stuck. He had to be accompanied shopping. With non existent bus service, he grew increasingly isolated.
So we looked at what we wanted. Wife wanted to be by the seaside, so we could have downsized to there. But where we live is fine - plenty of buses, major A&E hospital 30 minutes walk away, shops within walking/mobility scooter distance. We don't need to rely on being able to drive. Over the first lockdown, the car didn't move for three months!
But we both enjoy volunteering on the Talyllyn. So we bought a static caravan, and now we can enjoy staying by the seaside and working!
