One thing Spain has given my opinion on life is that the problems in the UK are not only in the UK.
I guess one of the pressures that we have compared to older generations is that of freedom of movement and information.
My parents travelled, but no where near as much as I do and everytime they did, they were more than happy to return home afterwards.
I`ve always stated that moving from the UK due to govt, hoodies, crime etc is not a good reason to move. These factors are in all countries in various degrees.
Believing the TV programmes are 100% accurate also doesn`t help.
Its not for everybody and very few no retired Brits stay in Spain for more than a few years.
The one piece of advice is don`t expect Spain to be the same as the UK, its far behind most EU countries in terms of culture etc etc.
