Men said they spent 13 hours a week on household duty including cleaning the washroom, taking out the rubbish and changing the bed sheets. But 60 per cent of the 1000 men questioned said their efforts were unnoticed by the woman in their lives because they did not like to make a fuss. Almost half said they felt women were more likely to show off about the amount of housework they take on. The task most men said they did was taking out the rubbish—with 85 per cent claiming credit. Carrying the shopping bags was the second most popular housework among men, with 80 per cent saying they take the weight off their wife’s shoulders. Food shopping came in third place—with 78 per cent saying they are responsible for restocking the fridge each week. The research by Dove, the beauty brand, found men spend 4.7 hours a week on housework as well as 1.5 hours on DIY and 6.9 hours on childcare. Paul Con-nell, brand manager of Dove Men Care, said that their research showed that modern men were becoming more vocal about the contribution they make in the home, and the popular stereotype of men doing nothing around the house is no longer accurate.
