Just watched a good BBC documentary about North Ronaldsay island in Orkney: https://www.bbc.co.uk/programmes/b0bbbz7c
Unlike a lot of these "island life" documentaries (look, cool landscapes, Gaelic dances, sheep etc) the programme was really honest about real life in remote areas, the challenges faced by those who live there, particularly demographic and economic issues, the way it's become a retirement place.
Definitely recommended if you have a spare half hour and have any interest in rural life.
