"You’ve likely heard that multitasking is problematic, but new studies show that it kills your performance and may even damage your brain.
Research conducted at Stanford University found that multitasking is less productive than doing a single thing at a time. The researchers also found that people who are regularly bombarded with several streams of electronic information cannot pay attention, recall information, or switch from one job to another as well as those who complete one task at a time."
