[Ganesh]

Do you suffer from motion sickness?
What is the meaning of motion sickness

[Milanya]

Motion sickness is nausea and dizziness induced by motion, as in travel by aircraft, car, or ship.
It usually affects people whose vestibular apparatus does not work properly.
Vestibular system - organs mediating the labyrinthine sense; concerned with our sense of balance. It is located in one's inner ear.
It is hard for a person who suffers this kind of problem to be a sailor or an airplane pilot.

I do not often suffer from it. Do you?
