There is an essay called "When we were insane." about sensory knowledge and response versus structure in one's life. I can't find it anywhere online. Its about the tradeoff between working in natural environment and relying on cues versus the highly structured environment of today where we rely on programmed activities. Some people cannot get the hang of being programmed and are seen as being insane, but when placed in the wild, are able to fend for themselves vs the modern programmed person who would die very quickly in the wild. Just thinking aloud.
