212man,
Remember the Black Marble Theory?
Our Brain is very much like a Jar of Marbles with a finite volume of knowledge it can store. All those Memory Bits are like Marbles of different colors connoting the importance of each.
Let's assume the Black Marbles are the most important and the Red Marbles are the next most important and the Pink and Mauve's are the least two important.
Should we not do our best to have a Jar full of Black and Red Marbles with as few Pink and Mauve as possible?
It isn't the Data Points about names and faces that is getting to you but all those Thousands of Bottles of Gulder you gulped down those Years ago that is getting to you.
