human brain the super computer

dear streemian
today I want to express my thought about the power of human brain . Yes no matter what are you doing , your brain always functioning either you are sleeping or in awake state .Your all activity either internal or external,Governed by your brain . Perception which develops your brain , will expressed through your activity . But the most of time you don't know how it happens .Because of autonomous mode of operation ,there are three types of function operated by your brain simultaneously. One Central nervous system,parasympathetic and sympathetic nervous system . You can say one automatic arrangement of your safety sympathetic will operate when you are in danger,and normally it is impossible to escape next parasympathetic , semi controllable activity like toilet,urinal , taking food , respiration and so on .
