INTRODUCTION
It is an amazing fact that the world's most used heat engine has only a thermal efficiency of 5.5%, its human body. It is almost impossible to build a machine which has similar functions of a human body. A human body can deliver immense response unlike any machine that man has made so far. It has the most energy storage capacity compared to its energy output. For example, even if a man gets starved for a week or so (proved), his body doesn’t stop any of its energy outputs.
It is not necessary to be physician to study our own body's functions and defects. The more one studies a human body functions the more will he get excited.
