A comedian recently quipped that today's information technologies have effectively rendered a number of things obsolete, most notably phone-books and human courtesy. That's also true for human rest.

Today's information technologies (the internet, email, software programs like Facebook, mobile phones, IPhones, pocket computers, and the like) have made us the most informed, efficient, and communicative people ever. We now have the capability, all day, every day, of accessing world events, world news, whole libraries of information, and detailed accounts of what our families and friends are doing at any moment. That's the positive side of the equation.

Less wonderful is what this is doing to our lives, how it is changing our expectations, and robbing us of the simple capacity to stop, shut off the machines, and rest. As we get wrapped up more and more in mobile phones, texting, email, Facebook, and the internet in general, we are beginning to live with the expectation that we must be attentive all the time to everything that's happening in the world and within the lives of our families and friends. The spoken and unspoken expectation is that we be available always - and so too others. We used to send each other notes and letters and expect a reply within days, weeks, or months. Now the expectation for a reply is minutes or hours, and we feel impatient with others when this expectation is not met and guilty inside of ourselves when we can't meet it.
