Have you ever thought about how much you see around you, all the experiences you undergo, the people you meet, and so on ? All of these are memories that we junk (after all, how many of us remember the persons who were in the elevator with us a week back) ? If you started remembering all that, you would be a person with a superb memory (many of us have problems with remembering the name of people we went to school with, or even those who were very close friends sometime back). Well, consider the case of a person (as part of an experiment) who saves all information, including the people he meets, the meals he has, the conversation he has, and so on (link to article):
But Bell, who is 75 years old, takes the idea of digital memory to a sci-fi-esque extreme. He carries around video equipment, cameras and audio recorders to capture his conversations, commutes, trips and experiences. Microsoft is working on a SenseCam that would hang around a person's neck and automatically capture every detail of life in photo form. Bell has given that a whirl. He also saves everything -- from restaurant receipts (he take pictures of them) to correspondence, bills and medical records. He makes PDF files out of every Web page he views.
Can you visualize recording your entire life, ready for you to play back whenever you need something. However, if there is something called 'information overload', then such a scene is a perfect example.
