Caffeine’s Affect on History

Legend tells of 9th-century goat shepherds experiencing a burst of energy after eating the cherries of the Rubiaceae coffee plant. Don't know if the goats consumed the plant, but goats love eating invasive plants and will chew on Thistle when goodies are scarce, so it's likely. Then, the story goes, an abbot from a nearby monastery concocted a drink from the cherries and it worked like a sort of a spiritual no-doze for monks during long meditations.
