It’s not a myth.
Mortality rate rises with maternal age.
In the UK, too.
But I don’t think it’s pregnancy, either, now.
I’m wondering if its a vaxx-related issue.
Though, interestingly, the latest age related mortality data for the UK isn’t available yet, though it was supposed to be released this month...
It’s not considered “high risk” to have a baby in your 40’s. High risk is a whole different ball game. And the increases for potential problems are minuscule, unless you live in a third world country or try some type Of risky alternative delivery like “unassisted” or whatever.
