Evolution of Coffee

i know more coffee drinkers than non coffee drinkers, and almost all of them require it as soon as they wake up. i imagine the first coffee drinkers were making java hieroglyphics on a cave wall somewhere, and the art form that evolved from following generations has taken on more shapes than i can recall. as we start a new year, i can't resist the urge to go back in time... even on my other blog. cheers.
