The Design of Speed and Precision
Studies show that it takes about a second to decide whether a person will do A or B. That's much too slow to make a successful typist or pianist. Good typists execute one key stroke every 60 thousandths of a second. A pianist can play 30 notes with each hand about every 40 thousandths of a second. How do they do it?
Then there is the precision of the microsurgeon who repairs structures in the body so small he must peer at them through a microscope. Part of the secret of this design is the muscle structure of each finger and the hand. The basic finger design begins with seven muscles. Your thumb has five additional muscles. And, believe it or not, your humble pinky finger has three more muscles than the basic design. The muscles don't work alone. The tendons of the hand and fingers add elastic force to the operation of the hand. Essential to making these elements work together with precision is your sense of touch. Your fingerprints add the ability to sense texture and forces with more precision. All of these elements combine with the brain which automatically thinks several keystrokes ahead of the typist's and pianist's keystrokes, resulting in the seemingly impossible abilities of the hand.
The human hand is a unique precision design that could only have come from God's hand.
