Scientific American: “Clues to the underlying causes of boredom have come from patients who suffer traumatic brain injuries (TBI). According to James Danckert, a neuroscientist at the University of Waterloo in Ontario, people with TBI often begin to indulge in riskier activities after their accidents. These activities might include taking drugs or jumping out of planes&mash;pursuits they pick up in an attempt to deal with their new and chronic boredom.”
