My PA Serkan kindly brought in a bag of Columbian coffee on Saturday. I wouldn’t call myself a coffee connoisseur, but I am rather fond of the stuff. I must say, though, the beans Serkan brought for me to try are quite shockingly powerful: I just had my first cup of the day and I can barely control my body (well, less than usual, I mean). I suddenly feel  full of energy. How can a few ground up beans in hot water have such a profound  effect? What a way  to start a week.
