For all the familiar family reasons, I smoke outside, in the back garden; there is nothing much to see out there, particularly at night, so I frequently find myself staring up at the stars. These are some of the questions I ask myself during my smoking excursions: Why are we here? Is there really someone Up There? What am I doing with my life? Would a single currency result in a loss of national identity, and would a loss of national identity result in a loss of personal identity? And so on.
