The choice of the country to move to is very subjective!
Personal priorities influence choices: the climate, the advantages, the priorities that each individual has, etc.
Furthermore, it is necessary to check whether you are single, in a couple, young, retired, with children, etc.
Even the aspect connected to work influences!
Are you looking for a place to live but also work?
Or rather, a destination for a good retirement?
The variables are many and it is necessary to do a cold analysis on what you are looking for and consequently, which locations best meet your needs.
