I am sure we don’t really need – need a washing machine. Clothes that are hand washed, turn out cleaner and better than machine washed. In earlier times, people would stay fit my doing house hold work. Now days, people use all modern gadgets that work on press of a few buttons here and there and then they go to the gym to stay fit… or at least have memberships to gyms they think of going to.
Necessity is not always the sole reason for doing things in a simpler way. According to this mail I read, it said “Laziness is the mother of all invention” I will have to say, that I quite agree with the statement. It is my laziness that I keep a scale behind my chair so I don’t have to get up from my study table when I want to switch on the light or fan. There is no necessity here, just plain old laziness.
