Isn't being cold the absolute worst thing on earth! Is your house old and poorly insulated as mine is in the country? We huddle around the log burner rather than put the heating up (we leave it on lowest all week for the pipes etc but turning it up for the weekend only while we're there barely has an impact until we're about to go AND the fuel price of course!!)... In fact, I often think I'm warmer outside than in when it's really cold as I'm so well wrapped up and MOVING!
How far are you from civilisation? I forget!
