We are truly wonderfully made. The hand is a prehensile, multi-fingered extremity located at the end of an arm or forelimb of primates such as humans, gorillas, chimpanzees and lemurs. But the highly mobile, functional and strong hand is a major distinguishing factor between human beings and non-human primates. The hand is an essential participant for activities of daily living, vocation and recreation. With the development of Braille writing, the hand can read for the blind, while with the Sign language it speaks for the mute. The jumbo jets, massive ocean-liners, and the skyscrapers are all works of the hand of man. When a skillful surgeon holds a scalpel blade over a patient, the life of that patient is in his hand.
