Sub-,un-,conscious?

conscious means you voluntarily did it. like if you pick up your pen, that was conscious because you did it on purpose. subconscious means you didn't control it. you have a subconscious mind that controls your heart beats and breathing, otherwise, someone might forgot to breathe. =P and unconscious...i think that's just the state of being fainted or sleeping. don't quote me on the last one though.
