Why does each person reach a certain level and then stop?

About 150 years ago, an Englishman named Francis Galton looked around at his friends and came up with a similar question. He observed and found that tall people often have high parents and low people, parents are also often low. And he did some experiments to find out why people are different in height.

One of his findings today is what we call genetic genes.

Children and parents

Parents with black hair often give birth to children with black hair. Parents have the ability to run fast, often children run fast. Shy parents often have shy children.

Likewise, siblings in a home also have similar characteristics.

'Are you like your brother or sister?', 'You look exactly like my mother!' are common comments everyone has ever met.

The human body has a special code, which is called DNA.

The reason everyone in the family is the same is what we call DNA.

We can imagine each person carrying a guidebook for the development of his or her body, which contains specific codes.This 'DNA book' this eye cannot read, but our bodies can read it. That code tells the body what to do and how it looks. For example, it states that our hair is straight or curly, our eyes are brown or green, but it also regulates how tall we are and how long it will stop.

The DNA of each other, no one is the same, unless it is two brothers or two twin sisters with eggs.

Each person's code bears many similarities to the parent's code. That's because parents pass these codes on to their children. Each person carries half of his mother's DNA code and the other half of his birth parents. If the adopted child has an egg and sperm, then that child will carry the genetic gene for the egg and sperm. So the code specifies that your body is tall and tall, that's because of your parents' code .

Although each person's DNA code is very similar to that of their parents, there is a difference. That's because everyone has their own experience.

Experience is a part of making people

Everyone has their own experience. Experience is what we do or what happens to us. Eating is also an experience.

Both DNA and life experiences make us tall.

Some experiences we share with others, and some experience we only go through alone.

In order for the body to follow the instruction manual, energy is required. The energy we get from food, and it's important to get it from nutritious food. Even if the code in the manual tells the body to be taller that we don't eat or eat less, eating unsuitable food cannot be high.

Getting sick is also an experience. Some diseases can make you grow slowly. Today, we are less sick than in the old days and we also have more nutritious food than they do. So we are a little higher than those of parents, grandparents, or more.

In short, both the DNA code and the life experiences make us tall .
