How to avoid motion sickness.

How to prevent motion sickness.
The cause of motion sickness is the contradiction between the information from the semicircular canals of the inner ear and visual information. That is why the driver never has the sickness, unless he reads a newspaper open. You have to look outside, otherwise close your eyes. If there is no window, or if you can not look outside the window for reasons such as the location of the seat, you close your eyes. That is to avoid the contradiction between the information of the semicircular canals of the inner ear and the visual information. In a bus, the first rows are the best places. Children easily have motion sickness in cars. That may be because the height of the vision is low. They only see the back of the anterior seat.
