The habit of multitasking could lower your score on an IQ test and cause other cognitive deficits. I even take my phone with me to fire off a few texts when I go to the restroom.

My productivity mystery was solved after reading "The Distracted Mind: Ancient Brains in a High Tech World," by University of California, San Francisco neuroscientist Adam Gazzaley.
