My memory started out shaky and has gotten worse as I have gotten older. When I coach my son’s baseball team and have a brain stutter prohibiting immediate recall of a kid’s name, I rely on work-arounds like “Let’s go CHIEF”. Not necessary when it comes to electronic devices of all kinds. Just about every electronic device has memory and some devices have full blown hard drives allowing recall of tons of stuff. There was a recent CBS investigative report of the sale of used copiers. I rarely am surprised but when I saw the kinds of information retrievable from a used copier in just minutes, I was stupefied. Bottom line, when getting rid of not just computers, not just PDAs, but any electronic device you need to wipe it clean before you expose yourself.
