The practice of marriage is practised in every culture which is associated with the union of the boy and a girl to which they are committed to spending a life-long relationship.
The studies on the preferences shown by the woman who has to get married have to look for the boys who are career-oriented which could provide a good earning to feed them and their family and fond of children to establish a family which will help develop the stronger relationship between them.
