Interesting Facts

The word milkshake was first used, in print, in 1885, but milkshakes were originally sold in bars as a cure for hangovers. It was like eggnog, made with eggs, cream, sugar and whisky. (The milkshake as we know it today didn't appear until 1922, at the Chicago Walgreen’s pharmacy. they whisky had gone and two scoops of vanilla ice cream were added to “malted milk”: a mixture of milk, chocolate, and malt powder designed for children and invalids.  By the 1930s, milkshakes were a popular drink at malt shops in the US, which were the "typical soda fountain of the period. In the UK they were known as milk bars, and they were encouraged by the Temperance Society, as a morally acceptable alternative to the pub, which is ironic when you realise how the milkshake actually started.)

Maths really can make your brain ache. (Researchers from the University of Chicago have discovered that fear of maths can activate regions of the brain linked with the experience of physical pain. In fact, the higher a person’s anxiety the more it increases activity in regions of their brain associated with visceral threat detection, and often the experience of pain itself. If I'm honest, German grammar has the same effect on me.) Source

Many aeroplane cockpits have cup holders. (Pilots are allowed to have beverages in the cockpit. Unfortunately this factlet came to light in 2011 when a pilot spilled coffee on the cockpit panel of a Boeing 777-200 headed from Chicago to Frankfurt, leading to a false hijack warning and culminating in the plane's emergency landing in Canada. I guess they've got to keep hydrated, but they should give them sippy cups.)
