Sorry about "sexual" instead of "s-exual". i missed that transformation. After a few attenpts to beat the "system", I finally cracked it and have modified my posting.
One of the things I didn't mention were the fogs - or rather the smogs. London had long been noted for its fogs (The Gershwin song, "A foggy day in London town", gives a rathe romantic notion) but smogs were much worse. Smoke mixed with fog produced a yellowish concoction known as smog or, colloquially, a "pea-souper" because it was thick and resembled pea soup in colour. It enveloped you, even got inside houses and, worst of all, got in your lungs, causing respiratory conditions. I suspect that pea-soupers happened in other cities and towns but the one that really grabbed public attention was the one in London at the end of 1952, known colloquially as "The Great Smog". Smog was not only almost impenetrable but also lethal. The number of deaths attributable to the Great Smog has been disputed but we're talking several thousands of people. Eventually, in the mid-1950s, the Clean Air Act was passed by Parliament, requiring the use of smoke-free coal and other fuel sources. It took a while for the benefits of the legislation to resolve the issue fully and, though I lived in outer London, I can recall going to school with a thick scarf round my face and a faint yellowish tinge to the fog.
It was literally and metaphorically a gloomy period.
