the UK average is 5.6, mine's 11.6 i thought i was ok - i switch lights off, i put a jumper on instead of cranking up the central heating.... looks like i'm going to have to knock the foreign holidays and fast car on the head. YEAH RIGHT!
it's flying that's done it for me, i've flown 3 times in the last year. plus i do quite high mileage in my car. oh well you can all thank me when the british summer is 90 degrees and there's palm trees everywhere
