We here at TKZ care about writers—how they write, of course, but also how they can stay healthy. Today I bring you some venerable wisdom on both counts. First, on health: Over at Project Gutenberg I happened upon the definitive treatment of the healthy side of coffee, published in London in 1721, with the snappy title of The Virtue and Use of Coffee With Regard to the Plague, And Other Infectious Distempers. We all know coffee gives you a lift in the morning, among other benefits. But until I read this little book, I had no idea of the number of infirmities a daily cup of joe can overcome. To wit: [Coffee] cures Consumptions, Swooning Fits, and the Rickets; and it helps Digestion, rarefies the Blood, suppresses Vapours, gives Life and Gayety to the Spirits, prevents Sleepiness after eating, provokes Urine and the Catamena. It contracts the Bowels, and confirms the Tone of the Parts, being drank after Victuals, provided it be fresh made; for if it stands but two or three Hours, it loseth much of its Virtue. … It is an effectual Remedy against Worms in Children; so that if the Mother drinks frequently of it when she is With Child, the Infant will not be troubled with Worms, during its first Years.
