Nowadays, with the latest technology and well develop logistics, people can have wide variety of food choice without making by themselves. But back in the old days, people will spend more time on cooking and  preparing food.  It is my firm belief that nowaday people will spend less time   for a number of reason, and I will develop these ideas in the subsequent paragraphs .

To begin with, nowadays people's life are getting busier, and people have to do so much things that consume their time to cook . I have to admit that my opinion on this matter has been profoundly influenced by my own personal experience. You see, my parents have a lot of work and things to manage in order to support me to go to college. I manage to cook by myself, but sometimes I have to do a lot of things to catch up the knowledge  learning from the school and in the weekend, I have a lot of sports event to do . Thus, I rarely cook by myself.  As a result ,my family have no time for making the foods . For this reason people in nowadays will spend less time on  cook or preparing.

Secondly, the food in nowaday has a wide variety, this indicate that you can buy or eat anything you want near your local area . Drawing from my own experience, near my apartment there are kinds of supermarkets and restaurant that allow me to buy kings of item to prepare for dinner . Moreover, the time for me to gat down the market will only take a few minutes. So, it's really convinient for me either for eating, or buything I want. It’s certainly clear to see why people in these days need spend less 

In light of the above mentioned reasons , I strongly agree with the idea that people will spend less time on cooking or preparing food in twenty years than they do today.  Because  of  people in nowadays with their busy life  don't have time to make the food. In addition, things we need  are getting more convenient to buy and prepare so we don't need so much time.
