The height difference between 157 and 180 is urgently needed.

Height refers to the vertical distance from the vertex (V) to the ground. Generally speaking, the unit is centimeter (cm), and "meter" (m) is commonly used. Height is the length of the longitudinal part of the human body, which originates from the longitudinal growth of the human body and is greatly influenced by genetic factors.

note:

The height development of girls is earlier than that of boys, and it grows rapidly at the age of 12- 13 and stops at the age of 19-23, while the height development of boys is later, and it grows rapidly at the age of 15- 16 and stops at the age of 20-25.

There are many factors that affect height, such as heredity, nutrition, exercise, environment, living habits, race, endocrine, sexual maturity (menarche age 18 ratio1height 5 cm), distant marriage, medical progress and so on.
