If you try to find a secular reason, one runs into serious problems, especially today when women spend only a small amount of time (as a percentage of total lifespan) as “mommies”, unlike the past when most women married soon after menarche, died before menopause, and spent most of the time in between raising children (and if she was lucky, maybe some of them would outlive her). Apikoresim try to find a reason, and end up going on fishing expeditins for heterim.
