name, rank & serial number

growing up the biggies were learning your phone number & address, I still remember my first phone number HA1-6..something, something, something okay maybe I don't exactly remember I'm old give me a break. These days kids have to learn the above and cell phone numbers, more than likely several cell phone numbers. And it struck me yesterday as C passed our email address to someone that it is some pretty handy info for kids to learn as well.
