not surprising really.  the women of my generation (yes, older middle boomer) gave birth much earlier, had more babies (yes you, the young adults of today are those babies) and did not routinely abort tens of thousands of our generation every year.

none of this may fit the narrative of post-modern, reproduction liberated, career minded womanhood, but ya know folks biology is what it is.  we'd better get on with fast track ramping up of immigration, especially of young adults and children, or we're toast.
