What causes it? The Brain. I mean I see that you are probably implying that it's not normal, i don't really believe that. As far as i can tell anybody can do it if they know what to do. Also It doesn't really shock me that it isn't tiring, that's really all about whether your brain is able to release the chemicals it needs to feel rested. It's very much like the way farmers alternate crops in order to keep the soil full of nutrients . Also the receptors in the brain do actually develop a resistance to various chemicals if there are to many of the same kind for too long if you have ever known anybody who drank a LOT and didn't seem to get drunk at all, then you have seen this first hand. Alternating between different states of consciousness almost certainly keeps the brain fresh. I also think some need help and some don't just because they happened to think in those ways. Some people need singing lessons some don't, some people are born in Norway others are born in Korea it's just causality. |
