I don't agree. Our perception of the world is colored in the gut and served to the conscious mind. When I was living in New York, the jingle of the ice cream truck draw me crazy, it was torture. But for kids, it was happiness because the gut microbes feeding on sugar send a message to the conscsious mind to buy the sugary stuff and they created an irresistible desire for it. This is all done in the guts. Some people can remain cool under any adverse situation because they have a healthy gut.
