Same thing here, except I live a few thousand kilometers away from London. When I am too lazy to wash the windows for a month or two, the next rag goes straight to the trash bin -- it's so black and soaked with soot you can't really clean it afterwards. It would be nice to see the inside of the lungs of someone who spent a life here.
