Now, correlation is not causation. It's possible that the parent's strong marriage does not *cause* the child's good prospects and performance, but rather that both are caused by some of the same socioeconomic factors
I like the idea that it's actually a reverse correlation- that stupid children with poor prospects and bad grades cause their parents' divorces.
Personally, I jailbroke my iPhone once, then ultimately decided it wasn't worth the hassle of keeping up with the break/update cycle. And once they released apps, I sort of forgot about it all together.
