Motion sickness: when there's a conflict between what your eyes see and what your inner ears, which help with balance, sense.
Your brain holds details about where you are and how you're moving. It constantly updates this with information from your eyes and vestibular system. The vestibular system is a network of nerves, channels and fluids in your inner ear, which gives your brain a sense of motion and balance.
If there's a mismatch of information between these two systems, your brain can't update your current status and the resulting confusion will lead to symptoms of motion sickness, such as nausea and vomiting.
For example, you can get motion sickness when travelling by car because your eyes tell your brain that you're travelling at more than 30 miles an hour, but your vestibular system tells your brain that you're sitting still.
You really ought to strike that one from your list.
