It is summer time, and the living is easy. You can, at last, indulge in what is surely the most enjoyable of human activities—doing absolutely nothing. But is doing nothing really enjoyable? A new study in the journal Science shows that many people would rather get an electric shock than just sit and think.
Neuroscientists have inadvertently discovered a lot about doing nothing. In brain-imaging studies, people lie in a confined metal tube feeling bored as they wait for the actual experiment to start. Fortuitously, neuroscientists discovered that this tedium was associated with a distinctive pattern of brain activity. It turns out that when we do nothing, many parts of the brain that underpin complex kinds of thinking light up.
