When I was a girl the experts told us that it was essential for your health that you sleep with the bedroom windows open at night. If you were lucky enough to have old fashioned sash windows they should be left open an inch or two both top & bottom for maximum efficiency in ventilation - the warm stale air would rise to exit through the top as the fresh cool air flowed in below.
I expect the Green police today would, if they could, haul you in for this breach of the insulation laws, this selfish enlargement of your carbon footprint.
In Macclesfield it is even worse. It will be the real police hammering on your door, interrupting your beauty sleep, to point out to you that open windows are dangerous, to your wealth if not your health.
