Bottles of fruit flavoured and low-alcohol soju are seen in this picture illustration at a pub in Seoul, South Korea, September 9, 2015. Professional women are driving a change in the way beverage companies look at South Korea, which hard-drinking men have made Asia's biggest alcohol consuming country on a per capita basis. As more women join the workforce in South Korea, a growing share of younger women are becoming regular drinkers, shifting consumption patterns in a male-dominated society where post-work drinking sessions are a staple of office life. Rising incomes and a greater interest in health also mean fewer Koreans merely seek out the cheapest way to get drunk. (Photo by Kim Hong-Ji/Reuters)





Grandparents take part in a child care class for them in Seoul, South Korea, September 1, 2015. It is not unusual for South Koreans to pay their parents to take care of their children.
