I heard a rumor (maybe myth) that part of the reason why serial killers phenomenon was very rare in the eastern hemisphere (in culture at least) is that it is hard to get the right circumstances given that most of the people lives and interact with a big family compared to the US for example. I did not read about that or search it though. But it is an interesting idea. That's of course not to say that this is the only benefit from living with family (if true). I think it is also economically makes sense because in many of these countries it is very hard for young people to find a housing where they live specially in the big cities where there is more opportunities. Also because of the centralized economy around capital city and a few cities it will but pressure on the housing market. Not like the US when there is much more diverse and spread economy. I really miss living close to my extended family and be like 1 hour from most of them. Where I never been alone in any circumstances. But here is the US, I feel lonely and I don't think I am the only one.
