It may appear that both the legs are in the same size. But researches prove that there is a slight difference between both the legs. When a survey was made when the legs were measured with those who come for joining the army, it was found out that both the legs were not of the same size to the people of 32%. There was a difference of more than ½ cm difference between both the legs. When it was surveyed with the people of China, it was found out that both the legs were of equal size to 80% of the people, one hand was longer for 17% and 3% were with longer legs. Keeping apart the slight differences, the length of legs and hands are more or less the same. Leg will increase its length, when the bones grow. If the bones stop their growth, the growth of the legs and hands will stop. Bone cells are created in the cartilage area of the bones. The growth of the bones will be there, till the bone cells are diluted. Except those who are ill, the bone cells will be created in the same size. That is why the size of both the legs and hands are of the same size.
