So there we are at last: something decidedly positive to be said for pollution!
Slobodan: your mind is getting dangerously close to the state of mine: we remember things that normal people would not, in the sense that one image triggers another. I think that in my case it's a kind of early warning system at work - a sense of threats I may be seeing that may or may not be there; thank goodness climate change isn't one of them: it is there, so that's both comforting and not comforting at the same time.
