cgar, you have lost track of what we were even talking about, you aren't bringing anything new to that conversation, we're done here until you say something relevant again.
FoxHound, yes, I do memorize phone numbers and birthdays of people close to me, as well as important numbers such as my local GP and some others, though it has nothing to do with this game. It is useful to know these things not having to rely on technology to do the job for us, especially if you find yourself in a situation where you can't use your phone and need that information.
That's just common sense though in my opinion.
