As a kid I knew every one of my friends phone numbers. I couldn't tell you my nearest and dearest now because typing this kind of info manually is long gone.
I've had to enter in my wife's phone number for various things enough times I know it better than my own phone number now (Meijer mPerks alone I've done it probably 300 times). But outside of that, my own, and my parent's phone number, which has never changed, I don't know any phone numbers.
I'm 50 and I can still tell you the phone numbers of all of my friends from growing up. The only number other than mine that I know now is my wife's because it's the number for the grocery store discount card. That stuff sticks because we pounded it in there.
