[关于人体的五大谬误]人体五大系统

　　你认为人只有五种感官吗？你认为舌尖对甜味敏感而舌根对苦味敏感吗？你认为惯用左手的人更具创造力吗？你认为你的胖瘦是由你的新陈代谢决定的吗？如果你的任何一个回答是肯定的，那么千万别错过下文哦！
　　1. You Only Have Five Senses
　　Sight, smell, touch, taste, hearing. They are your five senses. Since kindergarten, you"ve probably been told that anyone who thinks he has a sixth sense is either a psychic1) or M. Night Shyamalan2).
　　The Truth:
　　Scientists still aren"t quite sure of exactly how many senses you have, or what even constitutes3) a sense. Depending on how we count them, there are usually 14 to 20 of them. The five you learned about in school are just the five most evident senses. The rest are far more interesting.
　　For example, close your eyes, then touch your nose with your index finger4). How did you know which one was your index finger without looking at it? How did you know where your nose was? Did you smell your finger to your nose? No, that"s proprioception5), your body"s awareness6) of where it is in relation to itself.
　　2. The Tongue Map
　　One of the first things many of us learned in science class is that the tongue is organized like a factory floor plan7), with each region assigned8) responsibility for its own highly specialized9) tasks.
　　The Truth:
　　Researchers have known for years that all areas in the tongue are about equally good at detecting10) different flavors. It"s not an evenly11) distributed12) democracy of taste buds13), but every tongue has different patterns of strength and weakness. Each of our "tongue maps" will detect different tastes, sometimes from the same meal. Also, far from being relegated14) to specific locations on the tongue, your taste buds go all the way down your throat into your digestive system.
　　3. Your Personality Is Determined by Your Left- or Right-brainedness
　　If you have functioning ears, you"ve definitely been told at some point in your life that it"s very likely that lefties are artistically talented or emotional, and that righties are better at logical or intellectual thought. And it"s all because the right side of your brain (which controls the left side of your body) is totally in charge of your creativity, while the left side controls your logic.
　　The Truth:
　　It turns out that the whole thing about creative genius stemming from15) the right side of your brain is a big myth. The brain does indeed have some specialized structures that handle certain functions, but the idea that they cluster16) to opposite sides of the brain is ridiculous. Most brain functions work this way. Emotions (supposedly controlled by the right brain) and arithmetic17) (supposedly controlled by the cold, calculating left brain) both get the bilateral18) treatment. Scientists will tell you that in order to be truly creative or logical, you need resources from both sides of your brain.
