We’ve all experienced it — that vague feeling of aimlessness, restlessness, perhaps in the late afternoon; in a word, the doldrums. We experience it as background noise, but don’t really know what it is. It’s an unpleasant feeling that we seek to either eliminate or mask with external stimuli. And the stimulus could be anything as long as it’s colorful, animated, rhythmic, funny or engrossing: TV, YouTube, mischief, porn, movies, games, books, food or all of the above. We’ll do anything to get rid of it.
