Hormones can determine what the brain is interested in doing. In that context the law of nature is that women come to life to be a mother. This is the strongest instinct of most women and it determines what her brain wills. Mere career-related, or deep romantic things are only dreams of sexually immature woman’s brain, in most cases, of girl’s brain. In sexual mature period hormonal changes that affect woman’s brain cause a single woman to focus more on stable sexual relationships, find a lifelong mate and choose a career or job compatible with raising a family. Female brain cannot be comfortable, if a woman leads a single career-oriented life, even if she satisfies her sexual desires at random. The law of nature is that sooner or later after stable sexual relationships comes pregnancy that causes to hormonal changes which in turn make woman’s brain focus more on nesting and less on career. Then comes breast feeding period and accordingly, focus more exclusively on the baby. That is enough, isn’t that? Can woman’s brain return to her career-related dreams? But what about child rearing? It is not only social-cultural phenomenon, but also biological-physiological one that causes hormonal changes which in turn causes less interest even in sex, let alone in career, more worry about kids. The nature of female brain is that, no woman can avoid it, if it doesn’t lack motherhood instinct. Hot debates concerning women’s rights, freedom, activity and so on and so forth is product of female brain that lacks this instinct, or that doesn’t feel comfort of a nest and sexual pleasure in that nest in addition to motherhood.
