"Many people wish their memory worked like a video recording. How handy would that be? Finding your car keys would simply be a matter of zipping back to the last time you had them and hitting 'play.' You would never miss an appointment or forget to pay a bill. You would remember everyone's birthday. You would ace every exam. Or so you might think. In fact, a memory like that would snare mostly useless data and mix them willy-nilly with the information you really needed. It would not let you prioritize or create the links between events that give them meaning. For the very few people who have true photographic recall - eidetic memory, in the parlance of the field - it is more burden than blessing.   "For most of us, memory is not like a video recording - or a notebook, a photograph, a hard drive or any of the other common storage devices to which it has been compared. It is much more like a web of connections between people and things. Indeed, recent research has shown that some people who lose their memory also lose the ability to connect things to each other in their mind. And it is the connections that let us understand cause and effect, learn from our mistakes and anticipate the future. ..." - Keith Pelczarski
