A recent experiment held in Japan shows that it is almost impossible for people to walk exactly straight for 60 meters. Tokyo University of Agriculture and Technology found 20 healthy men and 36 them to walk as straight as possible to a target 60 meters away at normal speed. Each man had to walk on white paper fixed flat to the floor wearing wet colored socks. The footprints revealed that all walked in a winding   37   straight line. Researchers found that people  38 the direction of walking every few seconds. The amount of the winding differed from subject to subject. This suggests that  39  of us can walk in a strictly straight line. We walk in a winding way mainly because of a slight structural or functional imbalance of our limbs. 40   we may start walking in a straight line, several steps afterwards we will have changed the direction.

When you spin, the liquid inside also spins. The difference is that when you  44 , the liquid continues to spin for a while. Dizziness is the 45 of these nerves in your inner ears. When you open your eyes, although your eyesight tells you to walk in a straight line, your brain will  46   your ears more, thus you walk in a  47  line.
