and which explains a great deal...
We absorb a great deal of information from our surroundings, our environment, the media, the books we read, the movies we see etcetcetc.....Some of it stays, some of it disappears altogether and some of it gets hidden to surface at a later point of time. How we process all this information inside of us depends on what we are all about. This is then what becomes the body of our knowledge....Fantastic, isn't it?!
