Either way this and the finding that older parents are happier suggests a strategy: keep planning to have kids 'very soon', putting it off month after month until you're in your early 30s

LOL? I doubt if it's that easy to trick the brain. Add in the possible damage done by miscommunication ("I thought you said you wanted to have children this year", "No that was just a strategy...") and the very serious danger of postponing a bit too long and failing to have children even though it's desired, and this strategy looks like the product of a graph-reading robot, not an intelligent human.

Great article otherwise.
