GPS

Reality is we don't, aren't required to, use our brains anymore.
I bet most of you guys remember your home phone number from growing up and your 3 best friends as well. With a rotary or, "the latest", push button phone we had to!
Well, I can remember those clearly, but I don't know a lot of regular numbers I use regularly today. They are a name in a phone vs a number in my head.
