Back when I was a teenager and even before that I remember that at any given time I had probably a dozen or so phone numbers memorized. I never have to look up the number for my friends, or my parents work numbers. However, after owning a cell phone for the last 10 years I realized that I no longer have the ability to memorize any phone number after dialing it once. In fact, The only numbers I have memorized are my work numbers, and my wife's cell phone number. Even though I have called it countless times, I couldn't begin to tell you what my wife's work phone number is. Likewise, I don't have one single friend that I have memorized his or her phone number. Recently I found myself asking why this is. The obvious answer is as I get older and as technology improved, I have had no real reason to remember any phone numbers.
