Advantages of left-handedness include a strong sense of rhythm, good spatial balance, greater sensitivity to colors, etc. Disadvantages include the fact that it can be inconvenient to use tools in daily life, etc.
Research confirms that left-handed people have a well-developed right brain, with the right brain as the dominant hemisphere.
The two hemispheres of the brain have different divisions of labor, with the left hemisphere governing the activities of the right half of the body and the right hemisphere governing the activities of the left half of the body. The left and right hemispheres are divided into dominant hemispheres. The auditory center, language center and other basic functions are centered in the left hemisphere, while the functions of image thinking, perception, prehension and creativity are concentrated in the right hemisphere, and the right hemisphere mainly perceives non-linguistic information, such as imagination, music, graphics, and spatio-temporal concepts.
In view of this, relatively speaking, left-handed people with right-brain dominant hemisphere have a strong sense of rhythm, good spatial balance, and are more sensitive to color. However, since there are more right-handed people in society as a whole, most tools are designed for right-handed people, and left-handed people would have a great deal of inconvenience using tools.
