You still with me? Okay, here comes the payoff. The above study didn't examine which parts of your brain were most active while all this was taking place. So a groundbreaking scientist decided to see what parts do get activated when a person "broods." (Incidentally, the scientific phrase for brooding—that mental state in which we keep thinking about all the stuff wrong with us and our lives—is morbid rumination.) Generally speaking, it's not a good thing. Further, brooding is associated with an area of the brain known as the subgenual prefrontal cortex, which is very close to Delaware.
