I tend to agree with the theory that if you want to keep a memory pristine, you must not call upon it too often, for each time it is revisited, you alter it irrevocably, remembering not the original impression left by experience but the last time you recalled it. With tiny differences creeping in at each cycle, the exercise of our memory does not bring us closer to the past but draws us farther away.
