The Autumn of the Multitaskers

[..] certain studies find that multitasking boosts the level of stress-related hormones such as cortisol and adrenaline and wears down our systems through biochemical friction, prematurely aging us. In the short term, the confusion, fatigue, and chaos merely hamper our ability to focus and analyze, but in the long term, they may cause it to atrophy. The next generation, presumably, is the hardest-hit. [..] They’re the ones whose still-maturing brains are being shaped to process information rather than understand or even remember it. This is the great irony of multitasking—that its overall goal, getting more done in less time, turns out to be chimerical. In reality, multitasking slows our thinking.
