When was the last time you had to remember someone's phone number? I'm dating myself here, but I'm part of a generation that when you wanted to call your friend down the block, you needed to know their number. Can you still remember some of your best friends' numbers from childhood? What about the number of the person you talk or text with everyday? You no longer have to, because your mobile remembers it for you. This is not to say anyone wants to or should memorize 200 phone numbers, but we've all but lost the ability to remember a new one, or a conversation we just had, or the name of a new potential client, or something important we need to do.
Neuroscientist Manfred Spitzer uses the term digital dementia to describe how overuse of digital technology results in the breakdown of cognitive abilities.
