A husband creates seven additional hours of housework each week for women -- but when men get married, it saves them an hour a week when it comes to household chores, according to a study by the University of Michigan's Institute for Social Research. In general, married women do far more housework than they would if they were single, while men do less. And the situation gets worse for women when they have children. Married women with kids do about 28 hours of housework a week, compared with their husband's 10 hours.
