at any one point in time im sure im using no less that 50% of my brain, this comes from nothing but i do feel that to be true, and by "me using" i mean, it is what is focused on what i consider focusing on something. As in typing this, thinking this in my head, and thinking about the music playing on my computer and the humming of my laptop, the light on the right of me, the slight pain i feel, and the tapping of my keyboard keys. And i feel that no more than 50% of my brain is concentrated on my functioning. that part of me which controls the heart, and other unvoluntary muscle movements, including those which occur due to my current motions, like moving my toe, or the movement of my fingers to type, and those caused from the changes in body posture which keep me erect and not falling. So i feel that at any one time there is somewhere between 50 and 100 percent brain usage, and that the amount is not measured in mass of useage, or connections, but it is used in the fact that about 50% of my actions are concious on some level, and 50% are, and while it may not seem like it, only a fraction of that 50% is something that im aware of at any one moment in time, and that is the part which is what i think with, that includes inner dialogue and memory tasks. so please, everyone, have at how im wrong.
