Why aren’t humans able to stand completely motionless?
Because standing requires motion. At the very least, you need to be alive, and your heart and lungs (at minimum!) will be moving to do so. With more complexity, maintaining a standing posture requires constant adjustment to maintain balance in a system that's constantly changing (read: internal m…
The Short Answer
Because standing requires motion. At the very least, you need to be alive, and your heart and lungs (at minimum!) will be moving to do so. With more complexity, maintaining a standing posture requires constant adjustment to maintain balance in a system that's constantly changing (read: internal movement, muscles getting tired, etc) – the computational power and motor coordination required to do so is immense, and isn't really useful for humans beyond staying roughly still, so there's no reason for us to have evolved such an "expensive" *perfect* balancing system.
