We've all been bored on the job at least once in our lives, but that boredom is actually very old human wiring. We constantly seek out new information to keep our minds sharp, and when tasks get repetitive we get bored and move on. But what if you can't move on? What if the tasks are your job and you have to repeat them day after day to keep a roof over your head? That, says London Business School professor Dan Cable, is why boredom has become an epidemic. Our brains aren't used to staying in their lanes, so perhaps that boredom is not a bug after all, but a feature.
