I just want to say that a lot of it is around economic drivers. We tend to go to the religious or the cultural, but really, sometimes it's just about survival, and this is a way that has worked for them over the generations.
Of course, now we realize that it's not. We're coming to that realization ourselves, but also, as you work with people and talk to them about it, they realize it too. But that's a long, long process.
