I grew up a coffee drinker in Southern California. By 1992, I was a member of The Dancing Goat Society. Let me explain. On a morning in Ethiopia, some 1200 years ago. Khaldi, a goat herder well known for his laid back manner, awoke to the sight of his flock behaving extraordinarily. The natty beasts were dancing a dervish, standing on hind legs and bleating a Dionysian rhapsody as if primed by the goat-god Pan. When Khaldi noticed some of them munching on branches of bright red berries he took it upon himself to do the same. Enlightenment was at hand. The berries tasted bitter, but soon Khaldi found himself exhilarated, clear-thinking and wonderously joyful.
