We usually like to dig our ears outside. First of all, digging ears outside can clean the ear canal, and second, digging ears can make me feel very comfortable. However, picking your ears also has disadvantages. If the technicians who pluck their own ears are not very skilled, it may cause the tools that pluck their ears to damage our external auditory canal. Frequently pulling out the ear will also destroy the environment of our ear canal, because earwax can help us resist many foreign bacteria. What's more, we can't guarantee that the external ear plucking tool is not disposable, nor can we guarantee that the tool will be used after disinfection. It is because I have been to the ear-picking shop with dirty tools that I got otitis media after ear-picking, and it will not be good for more than half a minute.
Therefore, we can't lend the ear-plucking tools to others at ordinary times to prevent cross-infection of bacteria in the ear canal. We don't use cotton swabs when pulling out our ears, because cotton swabs can't completely clean the earwax, and even push some earwax deep into the ears, leading to earwax blockage. But if we don't pull out our ears for a long time, it will also lead to earwax blockage, because not all earwax can fall off naturally. Therefore, we can't pay it every day, but we can't never pay it.
In a word, bacteria are everywhere in our lives, and we should consider the harm of bacteria in everything we do. For example, be sure to wash your hands before eating, because if you eat a lot of bacteria on your hands, it is easy to eat them when eating.
