Blood Pumping Mechanism of the Hoof (2020)
https://horses.extension.org/blood-pumping-mechanism-of-the-hoof/> An extensive network of veins called a venous plexus are located on both sides of each of the lateral cartilages and in the sensitive structures of the hoof. The compression of these veins by the plantar cushion against the lateral cartilages or the coffin bone against the hoof acts as a “pump” to force the blood up the leg and back to the heart.
A horse is an extremely sophisticated biological machine, but it has no idea what makes itself tick. It has some limited mental model of the world around it and that's about it. Humans fare little better, but at least can make inch-by-inch progress through scientific study.
Such a creature that knew and felt itself perfectly, could at any point inquire the status of its own glycogen stores in its liver, could diagnose and micromanage its immune responses, could introspect accurately and with infinite recursion upon its own thoughts, seems hard to imagine, because if one were to set out to design such a creature, naturally its complexity would have to scale with the complexity it is attempting to self-model. Perhaps there is some sort of upper limit to the consciousness:complexity ratio that makes closing this gap impossible. (Or perhaps there isn't, and that would be just as fascinating.)
If nothing else, I would like to read a Borges story on the subject. Such a creature might inevitably be doomed to the same fate as Funes the Memorious.
Access is possible, complexity limits what you can do with it.
It's like having a JTAG port on a chip with a lot of test access. You can read the state of most of the gates, but now you're overwhelmed with data. Processing that data takes more resources than the system being monitored.
At a larger scale, though, this starts to work. Modern industrial plants and cars have sensors all over the place, more than are really needed to operate the system. They're there to diagnose it.
Evolution really looked at this big long list of gastrointestinal diseases we as humans can suffer from, and thought that traumatizing amounts of random nausea, constipation, diarrhea, and tummy hurt would be enough for us to figure out when we're supposed to be eating more nuts and less berries, or whatever the hell. I hate it.
When reading dune there’s a class of women who can control their biochemistry in such a way that they can eg prolong lifespan, or anything else within the realm of feasible biochemistry.
Here I was like: how does the nervous system function in that way? How could signals from the mind control the behavior of molecules?
The mind cannot itself feel pain, similarly the mind has sensory limits within the body. As argued in a book called the body a guide for occupants: cancer is a very good example of a disease that our nervous system should be able to detect but for whatever reason we don’t, probably because cancer is something we can only now treat.
Not all of the body can be made legible to the mind.
Although maybe a better question: why don’t we have a dedicated organ that can sample blood with laboratory like precision and make anomalies available to the conscious mind beyond whatever faculties we currently have?
PS
One thing that definitely should be within the realm of conscious control: body fat. There are ways of forcing the body to metabolize more fat for energy and the biggest problem is managing excess heart (easily becomes lethal). But this could be super useful in cold climates. Imagine being able to literally burn body fat to stay warm? The amount of heat that can be released is enormous. Nowadays most of us could probably afford the otherwise superfluous expenditure of body fat (beyond essential functions).
"My triglycerides are at 220 mg/dL" is not a useful signal to a hominid banging rocks together.
Instead, what we got was the budget version, keyed for resolution rather than understanding: thirst (osmolality of plasma fluid), suffocation (blood acidity induced by excess CO2), and when all else fails, at least vague malaise as a catch-all "something's off, let's maybe sit down."

Non-shivering thermogenesis is primarily mediated by brown fat. It's how babies keep warm. Adults still retain some brown fat, and it appears spending time in the cold can stimulate its production. https://stagetestdomain3.nih.gov/news-events/nih-research-ma...

Brown fat is burned in the body by a protein called thermogenin (UCP1). The same process can be stimulated by the drug 2,4-Dinitrophenol (DNP), albeit to lethal consequences if you're not careful. I suppose the reason we can't do this at will is because our body can do it unconsciously for us better and more safely than our frontal cortex ever could.
Because random mutations and selective pressure has never lead to such a trait that persists in a population.
So when you say being aware of every detail of your design, that hinges on awareness in the realm of critical thinking - but all the while, parts of your body are absolutely aware and in control of every little detail. I'd even say, these "subsystems" send a notification to your consciousness if anything is outside normal operational parameters, which makes total sense: Surfacing only details that require immediate attention is a good strategy to control complex systems, and one that we apply to many superficial constructions as well.
Another fun aspect of this is that when you try to suffocate yourself by holding your breath for too long, you'll pass out. Why does that happen? Because your body switches off your rogue consciousness in an attempt to stay alive - because staying alive overrules your subjective experience.
I think the Buddhist had it right in this instance, if you want to understand yourself completely stop trying to know every little thing and just be aware.

To my ears, a lot of detail is hidden in "knowing what makes itself tick". The limit of human Umwelt, cognitive closure, is an arena I find fascinating.
Modern people tend to identify understanding with mechanistic explanations. Veins, glycogen, immune states, hoof pumps. These are interesting and satisfying to us. But does that kind of explanation satisfy only because we are apes with ape language and interests, leaving aside even that we live in a society that values those explanations?
If a horse-level intelligence existed, perhaps its most satisfying explanations would not be "I can inspect the venous plexus in my hoof," but something else. Maybe more proprioceptive: pressure, load, gait. Or maybe that's just still my primate prejudice poking through.
What would satisfy a horse scientists might seem opaque or insufficient to us, but maybe our biochemical account would seem equally beside the point to it?
Maybe there is no species-neutral answer to what counts as understanding what one is.
On a deeper level, I suspect that a "complete understanding" in an absolute or divine sense is infinite. Our perceptions are necessarily limited, only a model of reality. In order to understand in a way that helps us survive, we must filter out a lot of information that is not absolutely irrelevant, but is irrelevant to us. Even Funes remembered only that which is relevant to a human, that which he could perceive in the first place. He could not remember changes in magnetic fields, background radiation, subtle shifts in gravity.
Another very relevant Borges story is "On Exactitude in Science." If we could precisely model every physical law and even the precise distribution of matter in the universe, but this model conveyed to us no intuition or usefulness on a human level, can it even be called understanding? Instead we seek teleological anthropomorphic explanations in everything, and it's baked into how we discuss things. "Big cats developed powerful muscles to run fast and catch prey," "our immune system exists to keep us from getting sick," "rooks are worth more than knights," "the universe favors states with the highest possible entropy," "de Rham cohomology detects topological holes."
