Are you an "Elderly Gravid"?

The description really creeped me out.

I googled the term, and these short paragraphs under first link that welcomed me:

If you have thrown your dreams of parenthood into the chill of the laboratory,
this book will bring every memory to the surface. If you are thinking about
supplementing old-fashioned procreation with science, this book is a good
field-guide to what lies ahead. And if you are a woman in your 30s, this book
should ring like a warning bell in the night --- at 37, you move into the
"elderly gravid" cohort, and the chances that you'll become a mother start to
drop dramatically.

It continues with:

The lesson? Don't wait. In your early 30s and thinking you have loads of time? No. You don't. The articles that make you feel good about postponing pregnancy may be true --- but not for you. Unless, that is, you're looking forward to writing a check to doctors that could have gone to school fees, child care or a summer house.

Why hello there, elderly gravid. Want some calcium to go with your cane?
