Quick – name five close friends or family members. Now, recite their phone numbers, without looking at your smartphone.
Can’t do it? You’re not alone. These days, it’s rare to find someone who still memorizes phone numbers, when all you have to do is tap on a name in your contact list. We’re living in an age where everything is available at our fingertips, from your friends’ birthdays (Facebook will remind you) to upcoming events (set an iCal reminder), or even the last thing you purchased (Amazon tracks your last shopping spree, whether you like it or not). And researchers say our brains are getting lazy because of it.
