The idea of the morning person aside, morning commuters seem to fall into one of two categories: the Caffeinated and the Un-caffeinated. Because, The Caffeinated are bright-eyed and engaged with the day's events already—they're reading their morning papers, or checking email. The line that runs out the door of the Starbucks across from my job never seems to shrink. Are the ranks of the Caffeinated growing? Will we soon be overrun by manufactured "morning people"? As the would-be Caffeinated stumble toward their favorite dispensaries, they have little sense of how they have been drawn to coffee-drinking.
