Pregnancy is, by and large, a healthy condition for a woman. (It is child- bearing that is dangerous, although much less so under modern conditions). Parasites feed off of you to your detriment, they do not cause physical changes which enhance your stamina and make you "glow".
So there is a certain short-term benefit (sometimes). Which balances the short-term sickness, aches, strains, and inconvenience? Longer term, would you say that the uterine damage, blood vessel damage, strained joints etc which can result balance whatever longer-term benefits there are? (I don't actually know if there are any). Women, in my experience, choose children despite the pains and sufferings of pregancy, not for its benefits... do you know many different??
I was using the term 'parasite' more as an analogy, attempting to represent the position of an unwanted embryo... but unless you can come up with long-term health benefits for the mother from pregnancy (including childbirth) I may have spoken even more truly than I realised. |
