Go look at the bottoms of your shoes. If one heel is worn noticeably rounder than the other, your body has been keeping a record of the problem for months. Frederick Schurger uses that homely little test because it's the cheapest posture analysis in existence, and because it opens the door to a bigger idea: where balance actually comes from, and what a chronically tilted body does to the brain over decades.
Where does balance really come from?
The eyes read the horizon. The inner ears read gravity and motion. Both true, both taught in school. But your brain also has to know where the body is underneath the head it's balancing, and that report comes from the suboccipital muscles connecting your skull to the top two vertebrae. They're so dense with position sensors that researchers describe them as a sense organ. We covered the evidence in Why most of your balance comes from your neck. Shift the structure they anchor to and the report goes wrong, the body compensates with twist and lean, and you become the person whose balance issues no ear specialist can explain.
What do posture problems have to do with dementia?
This is the part of Frederick's video worth sitting with. Cerebrospinal fluid pumps with every heartbeat, washing the brain, delivering nutrition, clearing waste. A structural shift at the top of the neck can disturb that flow, and fluid pulsing against brain tissue that isn't receiving it properly is not a neutral event repeated seventy times a minute for thirty years. In the brain stem the early signs look vestibular. Over decades, disrupted fluid dynamics keep showing up in research on Alzheimer's and dementia, which we summarized in Why disrupted spinal fluid flow is linked to neurodegeneration. What looks like a posture problem can really be a circulation problem. So no, uneven shoe wear isn't trivial. It's an early warning that costs nothing to check.
