Possibly. It seems a bit of a no-hoper until your glasses warm up, even if you can move them far enough down the nose not to catch much exhalation. Not even specialist anti-fog stuff seems to work for this situation.
I think going into buildings is a different and more difficult problem than outside moving use where there's at least an ample flow of dry air available to demist, so it's just a question of reducing the flow of damp breath across the lens enough to demist faster than it mists!
And having worked in £ S D, decimal is a doddle
On the one hand, I'm glad to have missed that one because my mental arithmetic depends greatly on how much I've used it recently... on the other hand, maybe it would have made my arithmetic speed better!
