Reminds me of people who remember everymoment of everyday for their entire lives. In one T.V. show, I think it was house, the person exclaimed that just becuase they remember every word in a book, doesn't mean they comprehended all of it.

Upon looking at this wiki: https://en.wikipedia.org/wiki/Hyperthymesia It seems it's some kind of obsessive disorder that causes them to remember it all. That's unfortunate as it could have been a great advantage for those afflicted.
