Some people marry for money. I am convinced that some people marry for smell. It's clear, at any rate, that many people do not get married because of smell.
People vary in the manner to which they let smell affect their lives.
Perhaps you aren't enthralled with the body odor of your husband or wife, but you go on living with them anyway. We smell the husband's mouth and ask the wife to do the same. In extreme cases, the spouse's malodor becomes grounds for divorce. Actually, according to ancient Jewish law, if a man marries a woman, and finds out after the marriage that her breath stinks, not only can he divorce her summarily, but he is exempt from fulfilling the terms of the marriage contract. Islamic tradition tells us about the sultan, whose breath was so terrible, that flies were afraid to come near his mouth.
