As a biped, we have a unique relationship with gravity. Our ability to remain upright and balanced is an amazing neural feat.be It is so ingrained that we do not notice its functioning whatsoever. Not even when the system is disrupted. Whether that be for a moment or chronically.
That system can be honed. It can be developed poorly. It can alter itself to adjust to an injury. And amazingly we can build new systems, with new rules, that operate in completely different ways than our bipedal balance system. Once we have new systems we can switch between them seamlessly.
