I definitely yield to you on that point. I was there for every moment of my wife's chemically induced labour and it was one of the most stressful days of my life. Not something I would want to go through myself! I read that a hormone (is it oxytocin?) secreted during labour has the effect of "flushing" short-term memory, so that the woman does not remember the pain as acutely. Something like this must be true, else no one would ever have more than one child.
