If you tend to get motion sickness when you ride on a bus, you might find this useful.
According to the journal Ergonomics, researchers at the University of Southampton in the United Kingdom wanted to know which factors were most likely to contribute to motion sickness. They analyzed about 800 bus passengers who complained of the disorder.
What seemed to matter most, they found, is where you sit and how the driver drives.
Their suggestion: Sit as close to the front as you can. The side-to-side sway is less in the front.
