Lee Jin-soo (C), 53, takes part in Happy Guys Cooking Class in Seoul, South Korea, July 31, 2015. After work on a recent Friday, Lee headed for the "Happy Guys Cooking Class," where he joined six other mostly middle-aged men in tall white hats and aprons. Lee is one of a growing number of men taking up cooking in a country where men have long done little housework. South Korean men came bottom in a 2014 Organization for Economic Co-operation and Development survey on housework, with just 21 minutes a day. With more women working in demanding professional jobs and households shrinking, meaning fewer women family members, many men no longer have the choice not to cook. Picture taken July 31, 2015.
