In this book Joshua you stated when thinking of an elephant you didn't see a picture - sorry but all my life whatever I think of I see - and I mean I see it as in real life - an elephant walking, a giraffe reaching up a tree - a car - or whatever - in full technicolour as it is in real life - with my eyes shut or open - in conversation or not. As to photographic memory - I did have an exceptional one, even at 77 years old it is still fairly good - when I studied - needing a certain piece of information I would call up the book in memory I needed, flick the pages until I came to what I wanted to read, and then focus on the paragraph I wanted. To a certain extent I can still do that (would you call that cheating?!!) and also know everyone of my families, and friend's phone numbers, addresses, birth dates etc., - and I have many many friends and lots of family. I still enjoyed your book, but could not remember by using the methods given! - yours Joyce.
