text: Einstein's theory of relativity figures in your question.  How we perceive ourselves turns on our metabolism.  If we stop to consider each breath, each step, etc. then we wind up unable to do the things we do automatically.\n\nWe have no idea how the hummingbird humms.. or the mosquito buzzes, but my guess is that it's autonomic and not thought provoked.  \n\nYou know the one about the centipede who was rambling along and a lady bug came up and was just mesmerized by watching it go.  "How do you do it," asked the lady bug? "Do what," responded the centipede.\n\n"You know.. manage all those legs.. fifty on the left and fifty on the right.. it's amazing!"\n\nThe centipede fell on his face.
