Are people nowadays are happier and more satisfied with their lives than people in the past? Some people hold the opinion that people now are less happy or less satisfied with their lives than people were in the past because the world is changing so quickly. I, however, strongly disagree with this opinion. And there are several reasons for this. To begin with, the fact that the world is changing so quickly does not make people less happy. On the contrary, it makes people happier. With the development of science and technology, more and more new technologies and inventions have been applied to our life to improve our life. For example, the internet and computer make our communication easier and more convenient. Only with software called Skype can we now communicate with anyone from any corner of the world; it is amazing, which is impossible in the past. Obviously, many new technologies and inventions have changed and improved our life to a happier level. Second, the reason why the world is changing so quickly is that people do their work more efficiently. In the past, people had to spend more time finishing a certain amount of work, while thanks to the new technology, people usually just need fewr time to complete it nowadays. For instance, in the past people have to write an essay with pen and paper, but now people usually write it with the software called Office in computer, which it is more easy to write, compile and revise the essay, and then it helps us save much of time. People can finish their work more effectively and more efficiently, so they would do other things with their time, and this would make them happier and more satisfied. Last but not least technology has been changing lots of things in our life, especially, they help people live longer and help people avoid assiduous work. With a healthy body and a simpler way to do their job, people of course can enjoy their life as well as their life more. For example, efficient transportation has helped people travel distant place within a very short time, while in the past they had to spend a long time to achieve this. And development of medical science has helped patients to cure once lathal disease. Remarkably, this is beneficial to everyone living in today's world. In conclusion, because of the improvement of life brought by developed technology, I think people now are happier and more satisfied with their lives than people in the past.
