Seems like the gas prices are the same in Sweden as some other European countries (Norway etc)..

Regarding the medical care, I believe it was ranked among the lowest in Europe a few years ago. If you have to visit a dentist, for example, it's sometimes cheaper to fly to Estonia or Latvia and get it done there and usually with better results.
Although, I haven't had problems with it myself, medical care that is, but this is what I've heard/been told and what the general opinion seems to be.

Maybe I shouldn't be too hard on it. Guess I had to find reasons to leave when there are quite a few good things about our country - beautiful women for example
