Sure but if I looked it up (Maybe later I will go and find the supporting evidence) those between the ages of 16 and 26 would be the ones that use the service most. They tend to have more partners, less wisdom and are not married. This of course is a generalization but the correlation is likely. I am sure that as with any distribution that those out side of one standard deviation exist.
And yet, marriage doesn't guarantee wisdom or any true commitment. Let's continue with the cliches and make reference to a middle-aged couple getting married in Vegas by an Elvis clone, after knocking back a few, and then possibly the dame gets pregnant and has to decide whether or not to get an abortion. A string of stupid, rushed choices lead up to the question of abortion. Moral to the story (however fuzzy it is); everyone has the capacity to make ill informed choices. And the bonds of marriage do not offer the certainty of anything.
