Coffee plays a very important role in modern society. As the rhyme of life increases people try to do hundreds of things and to be everywhere at once. The daily schedule of sleeping hours presents often a lame series of attempts to be awake when you want to sleep and to fall asleep when your head is filled with problems, plans and regrets of wasting your time on the night rest. In this mad world coffee appears to be a kind of fuel which most people use all day long to restore their energy. The whole coffee culture has developed and the coffee became a central image of it.
