In primary school age from 7 to 10 years, growth is slower. If earlier arms and legs grew more quickly, now the torso becomes the leader. It grows evenly, so that the proportions of the body are not violated. The next growth leap occurs in adolescence. Hands grow so intensively that the body does not have time to adapt to their new sizes, hence some clumsiness and wide range of movements. After that, the legs begin to grow. Only when they reach their final size, the torso is included in the growth. First, it grows in height, and only then begins to grow in width. During this period, the physique of a person is finally formed.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
