Why don't donkeys always get dizzy when grinding noodles?

The reason why people get dizzy after a turn is because when your body stops turning, the liquid in the outer lymph, that is, the inner ear, is still turning for a while, just like the soup in the jar will continue to turn for a second or two after you stop stirring. This small amount of liquid causes the hairy sensory cells at the bottom of the inner ear to bend in the direction of rotation. After a moment, the outer lymph stops rotating and the sensory cells called cilia stand up again. This lag time makes you feel that the house is turning. Dancers or figure skaters who turn around frequently stare at a distant point for as long as possible in each rotation. Her head is always the last part to turn with her body; As soon as she began to turn around, she immediately turned her eyes back to the same point. In this process, because the external lymph can't get enough strength to turn around, it prevents or at least reduces the feeling of dizziness and foreign body rotation. Moreover, the reason why the donkey is blindfolded is because it is afraid that the donkey will steal something from the ground. Blindfolded, it doesn't know it's spinning, so it can keep walking, otherwise it won't spin. It's not that the donkey won't faint, but because the donkey has been working without knowing it. Under the condition of blindfolding, the donkey will lose its sense of direction, and under the control of the reins, it will keep turning around, not out of the control of its owner, and it is very effective. Without knowing anything, blindfolded and under the control of the reins, the donkey will lose his sense of direction instead of not realizing that he will be dizzy.
