The strength of the right hand is greater because in our human habits, the right hand has more opportunities to exercise by lifting heavy objects. The right hand is more flexible than the left hand because it is used more often in everyday life.
For example, we write with our right hand, use chopsticks with our right hand, and play sports with our right hand... The more often the right hand is used, the higher the body's dependency on it.
Eventually, this forms a vicious cycle.
The right hand is dominant, and the left hand is secondary.
However, this is not the case in medicine.
The left hand actually corresponds to the right brain, while the right hand corresponds to the left brain.
The two hemispheres of the brain have clear functional differences.
The left brain determines a person's logical thinking, i.e., the rational side. Meanwhile, the right brain tends towards artistic thinking, i.e., the emotional side.
