Total tangent, but Malcolm Gladwell has two really excellent podcast episodes about memory (Revisionist History, season 3, episodes 3 and 4: http://revisionisthistory.com/episodes/23-a-polite-word-for-...). Basically, it’s WAY less accurate than we think, and the least accurate part is everything about time - when things happened, and even the order than they happened in. Worth a listen if you have some time to kill.
