The author of the article questions what is in it for a modern woman to monitor her husband's salt intake. Generations ago, women often measured their potential mate solely on the basis of how well he could take care of her financially because she would never have a means to support herself. In exchange, females would take care of the household and the health and well being of their husbands. The author feels short changed because nowadays women usually work outside the home as well as men and do not rely on their husbands for total financial support, although the women in relationships often still seem to be the ones looking out for the health and well being of the family.
However, it seems pretty clear to me that when I choose to cook a crisp spinach salad and grilled chicken for dinner rather than fried chicken and mashed potatoes, or when I remind my husband to schedule a dentists appointment - I am not only taking care of him, but of both of us. You see, the longer he lives, the longer a life (God willing) I will have with my soul mate...Seems like a pretty good trade off to me!
