C-sections (the C itself references Caesar) always remind me of the plot of Macbeth, and Shakespeare is a pain to read through the first time without feeling like you are going to die of boredom. I was always left better off by reading those works, so I guess that some painful experiences are worth it in life if you gain something from them. Childbirth by whichever means is painful for a woman but that pain is how it should be, and in all earnestness, a still-born, premature, disfigured, or disabled baby would be more of a worry to the mother as the act of birth is not so much about the pain as it is passing life along. The pain of childbirth is just the cost of happiness afterward.
Anyway, besides the obvious answer of the dominant side of the brain on most females being the side that processes emotions, why are women in general so emotional? Not that there is anything wrong with that, but doesn't it get old, even to yourself, when your reactions are so repetitious in ways that you would rather avoid?
