The body is a very sophisticated and complex organism. When taken cared of properly, the body's structures interact to help the individual function properly and effectively. Like any other structure, it must be cared for consistently to ensure efficient operation. Care for the body must begin early in life and be practiced throughout life. If the appropriate care is not given in the earlier stages of life, serious malfunctions may result later. Overall proper care involves several personal hygiene practices with the various parts of the anatomy. Health is a precious trust from God. To safeguard it is part of the stewardship of life. The World Health Organization (WHO) defines health as "a state of complete physical, mental, and social well being and not merely the absence of disease or infirmity", as Niere (2001) said.
