The Euro

I think a lot about the EU and the Euro. I know that sounds strange being that I live in Japan, but I always thing about the pound sterling when I write up my international travel lesson. Is England smart for not jumping into the Euro? With all the former soveit block countries clamouring to get into the EU, is the Euro in danger of instability? That was the view of one of the German guys I shared a hostel room with in Australia (along with a friend of mine, so don't get any ideas). He seemed like an intelligent guy and had a lot of informed opinions about the world. Plus he avoided bashing America to me, and thus makes up for a lot of the people I've ment on the JET program.
