In the glut of books and articles about single women waiting "too long" to "settle," or the collections of stats about how adults are getting married later and later, if at all, there is that one hard-stop, that one thing that often ends up answering the awful question of how old is "too old." That is, to make babies. Women have only so much time, those biological clocks are ticking, all of that stuff you've likely heard if you're in your 20s or 30s or 40s and are still dating and figuring out what you want. It's not untrue that at some point, women will have aged past the point of having babies, or at least, having babies easily. (Yet some still do: Take New York's ASME-award winning cover and related story, which asks, "Is there anything wrong with being 53 and pregnant?"). It's a topic we'll continue to discuss as technology helps women (and men) have children later in life, and it's a subject that's sure to draw strong opinions.
Regardless of any controversy-inspiring debate or magazine covers, science hasn't stopped working on its end of things. Technologies have emerged and improved to extend the years in which women can get pregnant and have babies, via in-vitro, surrogacy, and egg-freezing, among other methods that are continuing to be worked on and perfected. While some argue that older parents deny their kids a certain something—running around, maybe? But have you seen 40something moms in Park Slope?—others disagree, and at the end of the day it doesn't seem to matter; people, especially people with money, are going to do exactly what they want to do.
