Re: Appropriate use of icon..
I recall travelling to our neighbours before EU days
Admittedly, "before EU days" was pretty much the cold war, and there was all kinds of other crap to deal with. You know, like Germany being split across the middle by a bloody big wall and people getting their arses shot off for trying to cross over it.
Also the UK has agreed to some parts of the Schengen agreement. I think the healthcare provisions are one part. So, if you're in an EU country that isn't your home, and you fall sick, you can use that country's health service. Yes, even if you are a Pole living in the UK. I think there is even some provision where if you are ill in your home country, the domestic health service cannot help you, and there is a treatment elsewhere in the EU, you can travel to the other country and have your home nation's health service pay for the treatment.
It helped immensely with a friend trying to get on the Sativex program when he managed to say to the NHS guys in so many words, "marijuana is a treatment that works for my conditions, so how about I go to Amsterdam and you pay for it?"
He's on Sativex now, and yep, it works.
