When I was a kid in the south of Argentina, we used to say that if you dig a very deep hole to the other side of the earth, you will end up in China. In my case, China was literally on the other side of the planet; about as far from Patagonia as you can get. Thirty years later, I made it here. I didn’t come through a tunnel, but on a plane that flew over the North Pole.
