The story of the "Sphinx" mystery

The Sphinx is a winged monster in Greek mythology with the body of a lion and the head of a woman. Sitting on a cliff near the city of Thebes, he asked passers-by a riddle: "What walks on four legs in the morning, two legs at noon, and three legs at night?" If the passers-by couldn't guess, they were killed. Oedipus guessed the answer to the riddle, and the Sphinx jumped off a cliff to her death in shame.

In the morning of life, man is a weak and helpless child, crawling on his hands and feet;

In the year of his life he became a mature man and walked on two feet;

In old age, at the end of life, he needs support. So he set up a crutch as a third foot.

summary

Growth, development, aging and death are processes that humans must experience. After a person is born, his body gradually grows until he grows into a strong adult, and then his body gradually ages until he dies. This is an objective law. Generally speaking, a person's life goes through four stages of development: development (from birth to 20 years old), maturity (20 to 40 years old), decline (40 to 60 years old), and aging (after 60 years old). From birth to death is an inevitable process in human life. Human physical characteristics develop and change relatively slowly, and there is no obvious boundary between the physical characteristics of the two adjacent stages. Each stage of human development lasts relatively long, and the length of each stage varies from person to person. Each stage can be divided into several different periods.

Adolescence is the transitional period from children to adults.

Generally speaking, girls go through puberty earlier than boys, starting at about 10 to 12 years old, while boys start at 12 to 14 years old. However, due to great individual differences, the period from 10 to 20 years old is usually collectively referred to as adolescence.

Adolescence is a critical period for rapid growth and development of the human body, and it is also the second peak of growth and development in life after infancy. During this period, both boys and girls undergo many huge and wonderful changes inside and outside their bodies. Therefore, mastering and understanding the changes in the body during this period is undoubtedly a very important event for children to successfully survive adolescence.

Puberty refers to the stage when an individual's sexual function is from immature to mature. Biologically speaking, it refers to the transformation period of human body development from immaturity to maturity, that is, the transition period of a child from childhood to adulthood. Not only do physical changes occur during adolescence, but also psychological changes often occur.

The main characteristics of black people are: dark skin, dark and curly hair, dark eyes, broad and flat nose, thick and everted lips, less beard and body hair.
