The average age of China in 1949 was just over 30 years old, but in 2009 it was more than 70 years. Although there were many wars before, but there is also a factor which plays a vital role, that is medical technology.
From the historical process of human development, with the development of medical technology, we can better understand the human body and its possible health conditions, such as the invention of the microscope ,which contributed a comprehensive understanding of microscopic substances ,such as human cells; th discovery and application of penicillin saved countless lives; th applicationof medical equipment allows physicians to diagnose the patient's disease; th invention of vaccine enables humans to better prevent disease. Progress in medical technology has indeed made the threat to human health, such as diseases, timely prevented,diagnosed and treated, and the quality of human life improved as well as human life cycle extended.
Let's do a bold vision, along with the development of better medical technology, perhaps a few more years later, it will not be merely a dream for human to live to two hundred years or even five hundred years . Human cloning technology can be used to clone the organs needed to invent a universal medicine to cure cancer and other fatal diseases; we can also use gene technology to diagnose and treat currently intractable diseases. Perhaps mankind can really live forever, unless, 2012 end of the world really happened.
In fact, the current medical standards are far advanced to imagine, there are many incurable diseases threatening our lives. Therefore, we still have a lot of things to do, there is still a long way to go.

We all know that human life is very short before to see this picture, in 1949 China's average age, there were only more than 30 years, and in 2009 was more than 70 years of age. Although the causes of war before, but there is also a factor which plays a vital role, that is medical technology. From the historical process of human development, due to the development of medical technology, better understanding of the human body and its possible health conditions, such as invention of the microscope for microscopic substances such as human cells have a comprehensive understanding; penicillin discovery and application of saved countless lives; medical equipment application allows physicians to diagnose the patient's disease preparations; vaccine invention enables humans to better disease prevention. Progress in medical technology has indeed made the threat to human health, disease, timely prevention, diagnosis and treatment, to improve the quality of human life, human life cycle to be extended. Let's do a bold vision, along with the development of better medical technology, perhaps a few more years, humans live to two hundred years or even five hundred years will not be merely a dream. Human cloning technology can be used to clone the organs need to invent a universal medicine to cure cancer and other fatal diseases, using gene technology to diagnose and treat currently intractable diseases. Perhaps mankind really live forever, unless, 2012 end of the world really happened. In fact, the current medical standards are far advanced to imagine, there are many incurable diseases threatening our lives. Therefore, we still have a lot of things to do, there is still a long way to go.
