| Some people's ears produce wax like busy little bees. This can be a problem even though earwax appears to ? an important ?. It protects and cleans the ear, it trips dirt and other matters and it keeps in? out. Doctors think earwax also might protect against infections and the wax oil keeps ears from getting dry.
 So earwax is good, it even has a medcial name-cerumen, and there are two kinds, most of european or african ancestry have the wet kind, sick and sticky, east asians commonly have dry earwax.
