And, of course, all your phone numbers are stored in your phone so if you do get to borrow a phone, who are you going to ring?
I used to have a ton of numbers stored in my head (and can still remember the numbers of my two best mates from primary school). However, after 16 years, still can't remember my Mrs mobile number......
Same with directions, used to travel the length and breadth of the UK on my bike with nothing more than a few scribbled notes taped to my tank - now I rely on Sat Nav so much that part of my brain is defunct.
