I organize my memory spatially. I remember all of my thousands of CDs, but am clueless about the relatively small number of iTunes I have purchased. Papers spread out on my office and home floors horizontally, but I know where everything is and what it means. Each of my messes contains unreconstructible information.
My wife is a sweetheart, and my greatest terror is an overzealous maid.
If I lived in a small area, my mental life would be much poorer. That is also why I love driving around and why I do not care to live by the ocean.
