I was born in North London, grew up in Suffolk and came to Germany when I left school. Apart from a year in Cambridge as a legal secretary, I have lived in Germany ever since.
After over 40 years here, it's impossible to say what it's like living here. What exactly do you want to know?
Weather? Very similar to the UK, but more extreme heat in the summer and cold in the winter. (I am quite a long way down South)
Cost of living? Much the same as the UK, I think. Some things are cheaper, some are dearer.
Housing? People don't move house much. They rent till they're about 40 then they build a house and live in it till they die, leaving the next generation with a lot of hassle. Houses are about the same price as in the UK, if they ever do get sold, but they will have a cellar and be somewhat more solid and larger but with smaller gardens. Discussing and comparing house prices is just not of interest in everyday conversation.
Health care? It's getting worse as doctors are now retiring in their droves and life is being made impossible for young ones to set themselves up, or, if they are in hospitals, they are treated badly.
Unemployment is generally low but
criminality is on the increase.
The far right nationalists are gaining popularity.
Trains reputedly run on time, but huge numbers are cancelled, held up or run late. I would not risk going to an airport to catch a flight by train.
