@WashedOutGundamPilot What they don't mention about the births after 40 is that most of those women already had a bunch of children previously. All those times they were pregnant extended their fertility window. So it is not the same when a woman who is in her late 30s is trying to have her first kid.
While women are done a disservice by not being told the truth, many of them reject such advice and/or are willfully making the choices of delaying their search for a husband.
