Digital amnesia: Mobile phones deprive users of memory skills

"49 percent of UK respondents do not remember their parents’ telephone numbers, 57 percent haven’t memorized the number for their place of work, 71 percent of parents can’t dial their children off the top of their head, and 87 percent don’t know the number of their children’s schools by heart. On the other hand, 47 percent can recite the phone numbers they had when they were between age 10 and 15, likely before devices had such large memories."
