The life span of a building is determined by the strenght of its foundation. A major fault with a houses' foundation could lead to its collaspe. Likewise a cancerous cell in the body system would eventually affect other parts of the body if the cell is not detected early enough.
Science tells us that the human cell is the smallest unit of life, and sociologists say that the family is the smallest unit of the society. The family institution determines the sanity level of any society. It is from the home that values are imbibed into a child. Every family's role is to mould or shapen a child in the home and as the child grows into an adult they give back to their society somehow.
The family should be the major influence in a child's life and not leave this responsibility to television, books, the internet, games, schools and the likes. Dysfunctional homes have been proven by family counsellors and psychologists to be responsible for the causes of juvenile crime and all sorts of vices in different parts of the world.
How should we explain people who grow up to be suicide bombers? Personally, i think it has to do with the influences in the environment and this influence could be internal or external. Some parents do not have time for their kids and dump their parental responsibility on others and it is quite easy to be influenced negetively from the external environment, also there is the influence from within the home where parents display their hatred for one tribe or race without realizing that children are like computer programmes - garbage in, garbage out.
So if you are a parent and you are constantly in the habit of speaking ill of others, fighting your spouse just realize that your children will pick those characters after you. Therefore make a decision for your children, how do you want them to turn out? Think about this and let it guide you in your decision making process.
Remember this! A child well brought up would make the world a better place.
