I think the Cold War works as a great analogy or simile for different kinds of conflict. It's funny, when you look back at it, it's one of the last times that the boundaries were clear. Now, as we see on 'Homeland,' there are no clear boundaries and enemies.

I have very fond memories of the '80s; they were very formative years for me. I certainly remember the Cold War. It was a closer doorstep for the Brits than the Americans, so it was a very real and palpable threat at the time.

I first went to the Chubut valley, the colony that runs about 800km across the width of Argentina, in 2000. My uncle had been there tracing family and came back saying I had to go. So a year later I did.

I still dream about that one opportunity where the Welsh Rugby Union call me up and say, 'We need you.' There is an incredibly talented Welsh hooker called Matthew Rees, so maybe some incredible quirk of misfortune for him would mean I get called up instead.
