In 1942, a French researcher conducted research in the city of Paris on crime, and it shows that 88 % of the criminals came from separated families.(4) In general, the reason for good conduct is correct family education, and, likewise, most social vices, which a person practices in his puberty stage; like jealousy and having an inferiority complex, laziness, dependance, selfishness, aggression, drinking alcohol and using drugs, telling lies, stealing, hypocracy and showing bad behavior toward his fellow being, all these are attributed to the family education and discipline which he recieved in his puberty stage.

Man's behaviour, morals and attributes grow, even though escaping from them and controlling them is possible. Thus, man is an existence having will, freedom of choice and power of change, although his education, if not undertaken properly, creates difficulties for him, and others may become victims of such erroneous education.

Hence, among the ways a man can understand his personality and the problems he faces or the positive side of his personality is that he should remember the nature of his first growth, and study the environment and atmosphere in which he grew up, in order to understand the source of his problems or the positive side of his personality. b.

Genetic Composition Studies and field researches performed on the conduct of individuals, particularly the abnormal and unnatural ones, like of those who were inflicted with sexual deviations, tribalism, aggression...etc. show that there are some biological, physiological, and hereditary factors which have an affect on the conduct of a person, as well as, other educative, environmental and communal factors.

Indeed, it is comfirmed, scientifically, that the endocrine gland and hormones have a great effect on a person, and their effect increases - both in males and females, in the puberty and youth stages. However, man, with his power, is able to change his stand and displace or divert his desires, selfishness and personal interests. These scientific studies confirm that the nature of the body structure of a person, and his composition, has an effect on his conduct and human behaviour.

Therefore, the bodily structure of both a young boy and girl, like beauty and power, or weakness, simplicity and ugliness, has an effect on their various behaviours.
