People living in ancient times had no alternative but to do housework manually. They fire the wood when they cook,they hand wash clothes with hands; they sweep the floor with brooms.

Now, modern inventions come as a great relief to people. We cook with electric cookers; we do laundry with the help of washing machines; a computer-controlled cleaner can assist us in almost all cleaning. These modern inventions facilitate our housework so much that we cannot imagine anyone can make do without them.

Furthermore, robots are under development for making our life easier: It is likely that people can be entirely liberated from tiring housework in the future
