When i was young, I had an excellent factual memory. I'd remember rules for dungeons and dragons, i could tell you the page, the paragraph and the nearby art to look for. As i got older i noticed that type of memory started to fade, and i'd remember things more procedurally - what things do rather than what they are. It takes me longer to find a rule in a book, but i have deep understanding of what that rule does, how it works. D&D is a silly example, but it happened for all sorts of things. I sometimes draw blanks on names or faces, but once i get the link back to a conversation we had, i can remember all sorts of details about the person. The memories themselves are probably built because of interest, a more interesting person is more memorable. But the transition from a fact based model of the world to a action based model of the world was kind of disturbing.
