I think it's wrong from a biological pov.. Women become less fertile with age for a reason. Also, it just seems so selfish, to have a child knowing you will soon leave them an orphan - hell, this woman may not see the child's 1st birthday. Now I know you can die any time, but an accident is a maybe, death from old age is a certainty and I think you owe your child more than to have them knowing you will not be there for them.
However, reading the article, it seems they live in some form of extended, or group family, so I assume there will be shared parenting and may be younger people there who will care for the child when the parents die.
But --- I think also that there are many people who 'shouldn't' have had children - me for example, I'm very fat so not able to run round after them, or do lots of things that a mum should - in total fairness to THEM, should I have had them? Financial - hell we couldn't afford to have kids but we did! Really, we should not have had children until or unless financially secure. I have periodic depression - should I inflict how that makes me, on children? Logically? No....list goes on.
(I am using my personal examples so people can't jump down my throat with the I AM THAT how very dare you imply I shouldn't have kids! )
My point is that I'm firmly on the fence.
