Here's an interesting experiment. Nicholas Carr, writing in The Atlantic, wonders if the Internet isn't damaging our brains. His thesis: as we read ever less and skim ever more, the circuitry of our brains is changing, making the damage real and irreversible.
Well, here's the challenge: The article, at 4,200 words, isn't particularly long, but it's far longer than your standard Internet item. So, set aside some time - 10-15 minutes should suffice - and see if you can read it from beginning to end without stopping, and without doing anything else at the same time. Just sit and read (and hopefully, think about what you're reading). You might want to click on the "printer format" link first, so that your screen will be clean of distractions. Or maybe you'll want to really print it out, and read from some dead trees.
I managed to do it, but it wasn't easy. This is one of the reasons I'm seriously considering shutting down this blog sometime soon: to win back some time to read books. (The fact that I've been reading books at the rate of approximately one every three weeks this year is only because I've taken too many airplane flights, where my wifi doesn't work).
