The only numbers I know are the ones that haven't changed since before I was a teenager (basically just my parents' numbers and 911), my own Google Voice number, and Bing 411. That's partially because I can always look up numbers in my contacts, on Facebook, or online, and partially because I make phone calls less than once a week.

I don't bother remembering a phone number, unless calling that number will result in the person on the other end bailing me out of jail.

So far, 100% success rate.

in 2011 we do not know phone numbers anymore, but those braincells now store passwords.
