I'm sure every London blogger will open today with, "My God, it's cold". And they're right, you know, it's bloody freezing. Just a couple of weeks ago, Marcus and I were walking down to the RVT in T-shirts, saying, "I can't believe it's nearly December." Well, winter has finally arrived with a vengeance. The BBC's asthmatic weather girl gasped with glee this morning: "The maximum temperature today is two degrees, but with the wind-chill factor, expect it to feel more like minus ten!" On my walk down to the tube station, the wind was really biting. I felt as though my ears were being attacked by a school of razor-toothed piranhas.

Piranhas that don't live in warm, tropical places - or swim - clearly.
