Myth 3: You have five senses
误解三:人有五种感官
Children often learn that they have five senses - sight, hearing, taste, touch, and smell. That's a "fact" that originated in a work by the Greek philosopher Aristotle, written around 350 BC.
通常孩子们学到的知识是,人有五种感官——视觉、听觉、味觉、触觉和嗅觉。这一“事实”源于希腊哲学家亚里士多德于公元前350年左右写的一部作品。
However, you actually have more than five senses. Way more. In fact, scientists aren't even sure just how many more - estimates range from 22 to 33. Some of those other senses include equilibrioception (sense of balance), thermoception (sense of temperature), nociception (sense of pain), and kinaesthesia (sense of movement).
然而,实际上,人的感官不止五种,而是比五种多得多。事实上,科学家甚至都不确定还有多少种感官,据估计有22到33种。其他一些感官包括平衡感、温度感、疼痛感和运动感。
While none of these additional senses include the ability to communicate with the dead, some are absolutely essential for life. For example, our sense of thirst helps our bodies maintain appropriate hydration levels, and people who lack that sense - a rare condition called adipsia - can become severely dehydrated or even die.
尽管其他的这些感官不包括和死人交流的能力,但有些感官对生存至关重要。比如,我们的口渴感觉能帮助身体维持适当的水分,没有口渴感觉的人——这种罕见的病叫渴感缺乏症——可能会严重脱水甚至死掉。
