What is the primary purpose of marriage? To start a family. If your idea of marriage is that it is solely for those butterfly feelings or so that you can have the wedding celebration, you are more likely to have the marriage fail.
Yes, you need love to make a marriage work too. But that love is not in the form of shallow attraction that many mistake for love. The kind of love you need is the "this person will stick it out with me even when we can barely get any sleep due to a crying baby".
@houseoftolstoy a great deal of illness comes from the subversion/distortion of natural functions. Affluence leads to a carnival of addictions with the end being only gratification for its own sake, which exhausts the strength and faculties of the organism. Only discipline can solve this problem, either by the environment or by man's reason.
