This is the VOA Special English Health Report.

Some people's ears produce wax like busy little bees. This can be a problem even though earwax appears to serve an important purpose. It protects and cleans the ear. It traps dirt and other matter and it keeps insects out. Doctors think earwax might also help protect against infections. And the waxy oil keeps ears from getting too dry.

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.

But you can have too much of a good thing.
