That is so funny! I thought I was the only one who does not memorize phone numbers. When I was in college, psychology professor once said that our brain has a limited amount of "storage cells", so to memorize things that could be easily stored in a phone book is just spending those precious cells unnecessarily. Since then I stopped memorizing phone numbers. When a business contact asks me for my cell number, I always have to pull out my business card and hand it over- I do not know my own business phone numbers, cell or office.
E-books or actual real paper ones?
