Everyone talks about the “five” senses of man． And it is true that we get our information （信息） about the outside from our sense of sight, hearing, smell, touch and taste．Researchers tell us that the sense of sight – our visual sense –gives us up to 80% of what we know about the world outside our bodies; while the other senses, the auditory （hearing）, the olfactory （smell）, the tactile （touch）, and the gustatory （taste） bring into our brains information about the other 20% of what is happening． But there are two other senses that we cannot get along without, though they are little noticed． These are the senses of balance （平衡）, without which we would act like a drunk after a heavy drink, and the kinesthetic sense（动觉）, which gives us our ideas about our own motion （运动）．
