Some people's ears produce wax like busy little bees. This can be a problem even though earwax appears to serve an important purpose.
有些人的耳朵像勤劳的小蜜蜂一样分泌蜡状物（耳垢）。这可能是个问题，虽然耳垢似乎起着很重要的作用。

So earwax is good. It even has a medical name: cerumen. And there are two kinds. Most people of European or African ancestry have the "wet" kind: thick and sticky. East Asians commonly have "dry" earwax.
因此，耳垢是有益的。它甚至有个医学上的名字：耵聍。耳垢可以分为两类。大多数欧洲和非洲血统的人都是“湿润型”耳垢：厚而粘。而东亚人通常是“干燥型”耳垢。


注释：
