I asked Google. One article said social pressure: http://www.salon.com/2014/03/15/why_is_suicide_so_popular_in_south_korea_partner/ I just talked to someone in South Korea who said social pressure is a bit much there (not related to talk of suicide), that people work long hours in general and they take image so seriously that it's hard to not stress over it. She even said people take soap operas (K-drama) too seriously, and compare their lives to that, which seems a bit silly. If Thais did that Thai women would act even worse than they already do. The rate really is high in South Korea, on this reference list of rates: http://www.worldlifeexpectancy.com/cause-of-death/suicide/by-country/ I was surprised Thailand is so high as well, around 15 per 100,000 (compared to 20 for South Korea, and 10 for the US, which should be the standard for people being a bit off). I checked Nigeria, where the OP is from, and it's only 6, but of course an article on there says the same types of things, rates are climbing because of societal changes and pressures: http://www.nigeriaintel.com/2013/10/13/suicide-among-youths-sounding-the-alarm/
Interesting comment on the younger generation Perfectd!! I too noticed the obsessive behaviour of the kids over there, more so in the cities, but I think thats more a global trend. I have two girls here in NZ and they drive me insane with the phones and social media. My Thai partner is also slowly starting to get into it... I am afraid its me thats being left behind, but I am happy about that.
