I wish I can have photographic memory. Wouldn't it be so convenient if you could just look at something then be able to remember it? Imagine skimming the text book in one day and then know the whole thing the next day. School would be so easy. For piano you could look at a music score just one time and then you would be able to memorize the song. If we expand that further, imagine what would happen if you had video-graphic memory? wouldn't that mean that you could remember a whole series of events, so instead of remembering what the textbook looked like you would be able to remember the words when you read it line by line. For piano, you could go to a concert and remember exactly how the person played it. It would definitely be a dream come true!
