The subconcious controls our instincts. One of the examples I found most oftenly was the car driving one. Basicly it explains that when you are learning some thing you have to focus on it really hard and not have any other distractions, but after a while you no longer have to consciously think about it and it becomes instinctive. That is what the subconcious mind does it allows you to do things and yet still be able to be doing some thing else. One day when I was walking home from school (I was probably in fifth or sixth grade) I saw this tree that had grown into the sidewalk I had seen this tree hundreds of times and wondered if some one was walking and not paying attention if they would run into it. So I tried to distract myself and see if I walked directly into it, i didn't. I realized that with out thinking about it what so ever my body swirved around the tree, my steps nautaly moved along the curve of the sidewalk around the tree, even though I felt as if I was still walking in a perfectly straight line. This always puzzled and amazed me and now I know exacly why that happens. Our subconscious mind is a powerful thing that allows us to lead our lives the way we do.
