Having seen Finland for myself I cannot imagine why anyone would want to move to England/UK, certainly not the BIG cities, but I like you, prefer the smaller towns, mine has a population of around 45,000 and I am lucky enough to live right on the edge so I have a river 100m to my left and a canal and lake 50m to my right with open countryside in the middle but I can still walk into town in 10 minutes.
Maybe if I was 25 again the big cities would have more appeal but I am not …….. and they don't, although I do enjoy visiting, I really like London but that's because I can leave when it suits
Edit: As for vaccine's, they are looking to do everyone 50+ plus those younger with chronic underlying conditions and all key workers by Easter, yes it is a tall order and I am sceptical, I don't think they will be a long way off that depending on the availability of sufficient quantities of a vaccine but if I can have both of my jabs by Easter I would think they were doing OK and I am 60.
