Digital Overload: Your Brain On Gadgets

"Just as food nourishes us and we need it for life, so too — in the 21st century and the modern age — we need technology. You cannot survive without the communication tools; the productivity tools are essential. And yet, food has pros and cons to it. We know that some food is Twinkies and some food is Brussels sprouts.
