Have you had the experience, intentional or not, of being separated from the perpetual connectivity of email, IM, cell phone and text message? Maybe you've just decided to try a little connectivity 'detox' and deliberately withdrawn from instantly accessible communication, or perhaps you've gone camping and suddenly realized: hey, I'm really alone out here.
Years ago, I went on a sort of 'talking fast'. I went for a week without talking. It was surprisingly easy actually, but I wonder now if I could make it for a week without some form of electronic communication.
