Most people talk about the“five”senses of man．And it is true that we get our information about the outside world from our senses of sight，hearing，smell，touch and taste．Researchers（研究員）tell us that sense of sight-our visual（視覺的）sense-gives us up to eighty percent（百分比）of what we know about the world outside our bodies; while the other senses，the auditory（hearing），the olfactory（smell），the Iactile（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 them，though they are seldom noticed．These are the sense of balance，without which we would act like a drunk man，and the kinesthetic （運動覺的）sense，which gives us our ideas about our own motion（行動）．
