ABSTRACT
I am off-duty at home and settle down to watch a World Cup football match between Serbia and Montenegro and the Netherlands. I am not on call today, so I can relax a little for once. It is early summer and the temperature on this Sunday afternoon is unseasonably high; I have my windows wide open to let in the breeze and I am drinking a much-needed cold beer. The whole of Europe is suffering from a heat wave and the match commentators repeatedly refer to the ordeal that the players are going through out there on the pitch, grateful for the relaxed FIFA rules allowing them to drink as much liquid as is necessary to get them through to half-time.
