When science should mind its own damned business

In the "things nobody asked about" department, Dr Alan Cohen, "a part-time tutor at Cardiff University," has revealed why this Monday will be the most depressing day of the year. I think he misunderstood the chorus of that Boomtown Rats song; I, at least, didn’t really want to know why I don’t like Mondays.
Then again, since the collective does not embrace the new year’s resolution, it’s mostly the weather and those fiendish "General motivational levels" we have to worry about.

Maybe I'll Drink It While Knitting

From vol. 2 of the previously-mentioned book by Henry Mayhew, London Labour and the London Poor, a section on the River Beer Sellers or Purl-Men:
“It appears to have been the practice at some time or other in this country to infuse wormwood into beer or ale previous to drinking it, either to make it sufficiently bitter, or for some medicinal purpose. This mixture was called purl–why I know not, but Bailey, the philologist of the seventeenth century, so designates it. The drink originally sold on the river was purl, or this mixture, whence the title, purl-man. Now, however, the wormwood is unknown; and what is sold under the name of purl is beer warmed nearly to boiling heat, and flavoured with gin, sugar, and ginger. The river-sellers, however, still retain the name, of purl-men, though there is not one of them with whom I have conversed that has the remotest idea of the meaning of it.”

And from the Oxford English Dictionary:
“a. Formerly, A liquor made by infusing wormwood or other bitter herbs in ale or beer. purl-royal, a similar infusion of wormwood in wine. b. Later, A mixture of hot beer with gin (also called dog’s nose), sometimes also with ginger and sugar: in repute as a morning draught.”

From CocktailDB, a slightly more modern dog’s nose.
