Well, they include an awful lot that are about reciprocal medical treatment. How do I know? Well, I was standing at a bus-stop and a chap sidled up and whispered "pssssst, you'll be interested in these" and he handed me a couple of links. I rushed home and shoved them in the back of the computer, wound up the key and had a look. The first one is a terribly interesting agreement between the UK and New Zealand about being decent people to each other's people in that if I pop over to NZ for a wee look round and get sick the health service in that fine country will treat me and bear the cost. Similarly, if one of the All-Blacks forwards gets mown down by a Scottish scrum half and ends up in hospital then the poor fella will get treated in one of our hospitals and we'll bear the cost. That's what decent people do, isn't it? Interesting that this agreement was signed by Thatcher's Government.
The other link - well, the other link shows that this wee treaty is not alone. Medical treatment resulting from bad boogying in Barbados, crap karaoke in Kyrgyzstan or a misbehaving molar in Moldova will be supplied free or awfy cheap.
