There have been different opinions about the size of earlobe since ancient times. There is a saying in China that the bigger the earlobe, the happier it is. However, after modern medical research, it is found that these statements have no scientific basis. It can be said that the size of the earlobe is only a physiological development feature. In the process of our growth and development, many factors will affect the growth and development of earlobe, and the size of earlobe is also caused by genetic factors.
A large number of studies have found that the earlobes of people with longer life span are larger, so it is popular in China that the larger the earlobes, the longer the life span. Moreover, modern research believes that there is not much difference between humans and other mammals. Although the muscles and internal organs of the whole body have stopped growing and developing in adulthood, the ear is the only exception. It can be said that the ears of mammals are growing all their lives, with an average of 10 years 1.4 ~ 2.2 mm.
It can be said that the growth rate of the ear is extremely insignificant, but it is indeed growing, which is related to the organs of the body. Moreover, because the length of auricle is getting longer and longer with age, it can be explained that people who live long are not long after their ears are big, but long after their ears are long.
