Even two leaves are not exactly the same in the world. Of course, people should be tall and thin. Otherwise, all the girls in the street have long hair and can't recognize their girlfriends at a glance. Men and women are the same height and thin, so it's no fun to walk in the street. What should people who like to sit on the street and watch people do? Besides, people's age and development are of course different. You can't let a baby who just came out of the womb be as old as his father. It's so scary. All the mothers in the world will die in childbirth.

Then, in detail, why do people have the distinction of being tall, short and fat? It is divided into two parts, the first is height, and then is fat and thin.

Why are some people tall and others short? Because everyone's parents are different, this determines that everyone's genes are different. Genetic inheritance from parents has a certain influence on our height to some extent. It is generally believed that the children born to tall parents will be taller, and the children born to short parents will not be so tall, but this is only a part of the factors, which can not completely determine the height, and the genes will also mutate. It is not impossible for tall parents to have short children, so it doesn't necessarily mean that you are short if your parents are not tall. This acquired growth environment also has a certain relationship.

Human pituitary gland secretes growth hormone to promote our growth. When we are growing up, we can grow taller by eating less sweets, supplementing more calcium and exercising more. Anything is possible as long as you work hard. It doesn't mean that your parents are not tall, so you accept your fate. You will be shorter than others in your life. As long as you work hard, there is still hope to change. Under the comprehensive influence of many factors, people's height is not a fixed number, so some people will be taller and some people will be shorter.

So why are some people fat and others thin? When I was studying the course of cultural development in China, I heard the teacher mention that some people are particularly fat because they have spleen problems. When there is something wrong with a person's spleen, there is no way to absorb what he eats and then excrete the waste, but it will accumulate in the body. In this way, the more waste is accumulated, the fatter people will be; There is also a situation that something that is not delicious in the spleen will be directly excreted without absorption, so that people will look thin. Anyway, if a person is overweight, it means there is something wrong with his internal organs. Healthy people will look more symmetrical.

And everyone eats different things, has different nutritional values, and absorbs different things. Of course, the result of obesity will be different in the end, and children born in Lian Gang will not be so heavy.

Tall, short, fat and thin can have a wonderful life. As long as a healthy life is more important than anything else in this world, don't always worry about why he is taller and thinner than me. You should be confident that you are healthier than him.
