Even worse that me, wow!
I'm not LDS, but I live in Asia(it's mostly consider unproper to date before18, I think) Part of the reason we(asians)'re not allow to so is because what rev and Mat's Dice has pointed out "you're not mature enough"(and most of us aren't. setting a limit can ban those who think they're ready, but really aren't from doing so) and part of it is because adults think dating will make kids less focus on their study. (And university isn't a place for lots of study for some reason)
