We had something come up the other day, a point that we were arguing about how long ago something had happened.  Cords had the foresight to go back in to our Google Talk logs where we were instantly able to find when we had first discussed the issue at hand.  Life needs a feature like this.  Last week I was talking about how you would beable to implement this via a life camera.  If you were constantly recording everything that you were doing, you would beable to go back and search the archives.  We would also have to implement an auto-tag feature based on what you are talking about at the time, who are are width and location geo data or something.  There you go, instant life search is now available.  Imagine - Ctrl-F - "Remote Control"

Today, the first step was realized: Eye-socket camera that films from inside the head.
