Well, on the other hand, by that age you've probably both got pretty established patterns that are harder to break as part of your marriage. I don't think there's necessarily a "right" age to do it.
Wouldn't that also bias towards people who spent more time in a relationship before getting married? Personally, I would never get married with someone unless I dated them for at least 2 (preferably 3) years. I'm hoping that in itself will make it much less likely that I get divorced.
I just don't think it's a case where "studies show" is all that helpful. You're trying to get insight into a relationship with which you are intimately familiar by looking at aggregate data of people whose relationships are all over the map in various ways. It's like trying to figure out your risk of getting into an accident by looking at statistics for drivers in your age group without taking into account years of experience, propensity for speeding, and so on.
And that has nothing to do with the dating pool pre and post 30? All of my friends who are dating in their 30s complain about the typical dysfunctionally of the people they date.
