Earwax and unknown things

The composition of earwax in each person is basically the same, but it varies in color and texture. People in Northeast Asian countries such as China and South Korea are more likely to have dry earwax (hard earwax, color from red to black, or easily flake into pieces and yellow). Others often have sticky earwax, the color varies from orange to red orange.

According to scientists, this is one of many methods of creative protection of the human body . It is like a sticky trap, preventing foreign objects and bacteria from entering the ear. In addition, earwax can also clean itself, peel and fall off the ear. So, unless there is too much accumulation of earwax, we should not remove them.
