Can we walk out a straight line？The question is much more difficult to answer than you think．Believe it or not, your eyes and ears help you to walk！
A recent experiment held in Japan shows that it is almost impossible for people to walk exactly straight for 60 metres．Tokyo University of Agriculture and Technology found 20 healthy men and asked them to walk as straight as possible to a target 60 metres away at normal speed．Each man had to wear socks soaked with red ink and walk on white paper fixed flat to the floor．The footprints revealed that all walked in a winding rather than a straight line．Researchers found that people readjust the direction of walking at regular intervals．The amount of the meandering differed from subject to subject．This suggests that none of us can walk in a strictly straight line．Rather, we meander, primarily due to a slight structural or functional imbalance of our limbs(四肢)．Our body is actually semicircular, so steps by the left and right leg of a person are different．As a result, although we may start walking in a straight line, several steps afterwards we have changed direction．Eyesight helps us to correct the direction of walking and leads us to the target．Your ears also help you walk．After turning around a lot with your eyes closing, you can hardly stand still, let alone walk straight．It's all because your ears help you balance．Inside your inner ear there is a structure contains liquids．On the sides of the organ are many tiny hair-like structures that move around as the liquid flows．When you spin the liquid inside also spins．The difference is that when you stop, the liquid continues to spin for a while．Dizziness(眩晕)is the result of these nerves in your ear．When you open your eyes, although your eyesight tells you to walk in a straight line, your brain will trust your ears more, thus you walk in a curved line, or a spiral！
