人类一直以来认为，耳垢对人类历史没有多大的影响，但是现在日本研究人员发现，耳垢其实对人体也起到了一些微妙的作用。
3.Most East Asians also have a special form of a gene known as ABCC11, which makes the cells of the ear produce dry earwax.
而且大多数亚洲人还拥有被人们所熟知的特殊ABCC11组合基因，该基因令耳部细胞产生干耳垢；
4.People can also cause a blockage---when they are trying to clean earwax, but end up pushing it deeper into the ear.
