Having Invented technologies for preparing food, people wanted food itself to become faster to cook so now we have fast food. Fast food has a lot of advantages. It's very easy to cook, so it takes almost no time for you to make breakfast, lunch or dinner ready. And it doesn't matter whether you are a good cook or not because you need just to put food in a microwave and to warm it up. It can do even a child! Another advantage of fast food is in its cheapness. When we cook a dish we often have to buy lots of vary ingredients while fast food already contains everything we need so at the end we pay less.
