I believe that the human mind develops and evaluates its behavior
Customs and traditions change
Or open civilizations on each other negatively or positively
Sometimes by occupation or tourism and dealing
Or rampant corruption as it is today
The first nucleus of society is family
The family has changed from a mother ،father grandparent who has three or four sons
To a friend and girlfriend and a child in the nursery
All that changes every thing
Religion is a barrier to rapid change, but change in general is not
For example
