The senses are incapable of perceiving the full possible spectrum of radiation's affecting them, and lifelong exposure to a phenomenon serves to deaden the senses all the more - to the point where very little information is extracted from the impressions of things without giving much attention. By analogy, attention is a very magnetic property and is, therefore, easily attracted to things often of little import. Much energy is required in order to stop attention from sticking to every passing thought, feeling and sensation, and to choreograph their participation into a heightened perception of the entire moment; energy which we simply do not have at will. This is not so while bemushroomed - of course relatively.
