Sure. Can I ask the how many more kids they plan on having? Can I ask you the same question? Can I ask why that number is less than 16?

I spot two assumptions in your comment: 1) that families plan the number of children they have, and 2) that this planned number is some number lower than 16.

Yours is not the only worldview.

And with birth rates plunging worldwide, many now trending below sustainable levels, who will provide you with healthcare and other services in old age?
