Being a homemaker in the developing world frequently involves a lot more physical activity than in the developed. Food and water are usually a lot less convenient, and may involve travel. Homemaking may also involve farming, and taking excess food from the garden to market which again, often involves travel.

Also, the physical effort involved in being in the workforce in the developed world can be almost nil. A lot of people have to stand up all day, or pick up boxes, but that's far from subsistence farming or hand-washing clothes.
