I've been hearing that our very brains have more computing power than the highest of computers. IS this true. I mean what do we d o that's all that complex with out brains. I know consciously we don't have very much math ability but unconsciously we do. By the way, which mental activities use the most working of our mind? I also hear that there are more conversations from the left and right side of your brain than there are from North America to Europe per day. I wonder if we use much power as we sleep. Seeing that computers have millions and millions of transistors on one microchip and process extremely hard programs I don't see what we do that's so fantastic with out minds.
