Fortunately I'm not addicted to an iPhone—but only because I don't have one. I do, however, tend to go through withdrawal if I don't have my iPad with me. It turns out, these gadgets have become so much an extension of ourselves that scientists have found that we suffer cognitive and physiological impairment if we're separated from them. A new study by University of Missouri researchers put iPhone users in a situation where they were separated from their phones while taking a cognitive test. Not only did they do worse on the test compared to their performance when they had their phones with them, they also had a significant increase in anxiety, heart rate, and blood pressure.
