July 14. Continuing from the last post, Baltasar comments: "I think that ultimately your bones and muscles already 'know' how to stand up with good posture."

I'm sure a lot of people feel that way, but I don't think it's the bones and muscles. When people have good posture without even trying, it's because a subconscious part of the brain is working it out for them, or it could be nerve cells in the spine or something. But there's a limit to what the subconscious can do, which is why professional athletes are always working on form, and why nobody goes into a yoga class and gets the poses right on the first try.

My subconscious brain just has a lower level of what it can take care of. I can stand and walk without thinking, but to stand straight and walk non-clumsily, my muscles need a lot of coaching from my conscious brain.

More generally, it's tempting to romanticize mindlessness: all you have to do is not think, and your subconscious is magically omniscient. In reality, there's no shortcut for doing hard things. This is a 2017 article that I posted a few months ago, The true expert does not perform in a state of effortless 'flow'. It feels good to shut off your conscious brain and go on instinct, but to perform at the highest level requires a state of critical self-reflection, a careful balance between conscious and subconscious.

Matt comments:

From having studied massage therapy, I think the body adapts to whatever the mind is doing with it, for good or ill. If you sit for hours per day, the body learns that's its default position. The body doesn't "know" how to go from sitting hours per day to perfect posture. The body is a dynamic semi-solid system shaped by whatever is done with it.

In the same way, I think, our brains don't "know" how to concentrate. Our brains are artifacts of how we interact with reality. I do think consciousness itself has a quality of centeredness, but experiencing that centeredness (or connectivity) doesn't necessarily rearrange our brains so that we're perfectly happy.

July 12. Moving from the brain to the body: After years of struggling with posture, I've finally figured out the correct instructions. In Tai Chi, they say to pretend there's a string at the top of your head that your body is hanging from. While that's not unhelpful, my body needs something less suggestive and more concrete. A lot of people say to pull your shoulders back, which is the right kind of instruction but completely wrong.

This is what I'm doing. First, stand normally. Second, tilt your pelvis forward as far as you possibly can. Another way to think of it is to tilt your belt buckle upward. Third, raise your breastbone as high as you possibly can. Now, while maintaining those extreme stretches, walk around the room. I wouldn't do this in public, it would be too silly. This is basically the George Jefferson walk. But as an exercise, it's working much better than anything I've tried before. Now I just have to remember to do it more of the time, and work on smoothness.

July 10. Some fun brainy links. Skunk Ledger is a blogger who I can't even summarize. But most recently, there's a satirical Opening Speech for a conference of neurotypicals who feel left out by the coolness of nerds. And Superrational is the story of a ridiculously rational teenage girl, written in the style of Twilight fanfic.

And a fascinating Hacker News thread about crossword puzzles with multiple solutions. I wonder if reality works the same way, if the field of whatever, from which we extract sense data and construct the world, could be interpreted as something radically different.

July 7. Psychology links. Mental Liquidity is about the skill of changing your mind, and not letting your beliefs become part of your identity.

Intelligence and thinking speed: Surprising relationship revealed: "The study discovered that people with higher fluid intelligence, which is a measure of problem-solving ability, actually took more time to solve difficult tasks compared to those with lower fluid intelligence."

The explanation is related to the distinction between System 1 and System 2 thinking, where System 1 is fast and automatic, and System 2 is slow and deliberate, but more accurate.

And an article on Brain bandwidth, the brain's limited capacity to do careful observation and processing.

July 5. Last night was the annual blow shit up holiday, and I wonder, what is it about humans that they can never get enough stimulus? If there's reincarnation, in my next life I'd like to be a tuft of bunchgrass in an obscure canyon, just to get a rest.

July 3. This blog has not been a high priority for me lately. I've been putting more mental energy into writing fiction, making music playlists, making custom spirits for Spirit Island, and what I'm going to call "altered state of consciousness exercises".

The other day I picked up the classic 1969 book Altered States of Consciousness, and opened to a section on meditation. Everyone knows that you're supposed to "be here now". But be here now with what? A suggestion was to be here now with whatever you turn your attention to, when someone asks "How are you?"

If you succeed in being present, you can ask yourself this question: What's more troubling? That this moment will be completely forgotten? Or that it will never be forgotten? I'm sure people will answer both ways. The point is that it has to be one or the other, and neither one is something we go around thinking. And either one, if taken as true, will bring your mind into the present moment, whether to appreciate it before it slips away, or because you don't want to look bad in the Akashic records.
