So I was taking a while to get over Christmas and then I got a cold. The worst has passed but I'm still knackered and thought I should explain my silence in case anyone thought I had been gone up with a New Years firework.
Also, can I just point out that a cold spell brought about by an Arctic wind does not make for Arctic temperatures, as we are widely reported to be experiencing? It has to be said. It may be parky out, but it's about 4 degrees C here just now. It's currently -43 C at the North Pole.
