Looks like you are all busy. 5 kilos is good going Dave. Well done!
Mouse have you thought of a standing desk? I've sort of 'fashioned' something at home that means I can work standing up. I had a bit of a shock when I bought a polar loop thing and realised how many hours I spent sitting down! Im sure standing would be better for your back??
I'm STILL coughing, but am training now because this irritating post lurgy cough can last for yonks with me!
I too am feeling the cold today, but by the looks of my turbo set... I shall be warming up pretty soon!
