Problem description:

Especially eyebrows ... not just for expression, right? ..

Analysis:

Eyebrows and eyelashes form two lines of defense to prevent foreign objects from entering the eyes. When it rains, there are raindrops on eyebrows and eyelashes; When sweating, the sweat on the forehead is dirty, blocked by eyebrows and eyelashes, and rain and sweat can't enter the eyes. Eyelashes can also prevent dust and flying insects from entering the eyes. When strong light shines, eyelashes block the strong light like curtains, which weakens the * * * effect of strong light on eyes. These are the physiological functions of eyebrows and eyelashes. Maybe the students didn't feel their efforts.

Starting from the physiological function of protecting eyebrows and eyelashes, it is not advisable to shave off eyebrows, which removes a line of defense to protect eyes. Maybe some women think beauty is more important than eyebrows. Female students, cherish the eyebrows brought by your parents and don't take them off easily. Some children have the habit of pulling out their eyelashes, which is of course wrong. Not only did they lose their long eyelashes, but they also had wounds on the edge of their eyelids, which made them unclean. Bacterial infection may occur, and a small abscess will grow, and the problem will be complicated. We must get rid of this bad habit. Some male students ask for longer eyebrows, while some female students ask for longer eyelashes. There is no way to make the eyebrows or eyelashes themselves longer. Maybe students will ask, hair grows so fast, why are eyebrows and eyelashes not long? In fact, eyebrows and eyelashes have also changed, and they are also growing, but the speed is extremely slow. This is also the arrangement of the whole body physiological needs, which is good for people's health. If eyebrows and eyelashes are as long as hair, avoiding becoming monsters will not only fail to play a good role, but also bring harm to health. Needless to say, the eyes will lose their physiological function of seeing things, because there is a curtain composed of eyebrows and eyelashes hanging in front, and it is very troublesome to open the eyebrows and eyelashes with both hands when seeing things! This can only be used as a joke, but it also illustrates a problem. The growth of various organs and tissues of the human body is completely arranged according to the physiological needs of the human body, which is very scientific and ingenious. We can't be as small as we want, as big as we want, as long as we want, and as short as we want. Of course, some can be modified manually. But it must be noted that it will not affect physiological phenomena or health.
