What's that number? Come on, think!
Hey, cellphone user, when was the last time you memorized a phone number?
If you're like some of the 176 million mobile-phone subscribers nationwide, it may have been before you got your cellphone, because — perhaps unintentionally — you've become reliant on the gadget as both a communication device and a phone book.
Dr. Edward Tenner, author of technology books like "Why Things Bite Back: Technology and the Revenge of Unintended Consequences" and a senior research associate at the National Museum of American History, traced part of the problem to the rise of 10-digit dialing, which is almost a necessity now, even for local calls.
The human memory is best suited for recording information up to nine digits long, he said, but a phone number and its area code are 10 digits, which exceeds people's levels of comfortable memorization. "And that has all kinds of consequences," Tenner said. (Via Globetechnology)
