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 to a comprehensive understanding of microscopic substances, such as human cells; The discovery and application of penicillin have saved countless lives; The application of medical equipment enables doctors to diagnose patients' diseases; The invention of vaccines enables human beings to better prevent diseases. The progress of medical technology has indeed prevented, diagnosed and treated diseases that threaten human health in time, improved the quality of human life and prolonged the life cycle of human beings.
Let's make a bold assumption that with the development of better medical technology, maybe in a few years, it will no longer be just a dream for human beings to live to be 200 or even 500 years old. Human cloning technology can be used to clone organs needed to invent universal drugs to treat cancer and other fatal diseases; We can also use gene technology to diagnose and treat diseases that are difficult to cure at present. Maybe human beings can really live forever, unless the end of the world really happens at 20 12.
In fact, the current medical level is far more advanced than expected, and there are many incurable diseases threatening our lives. Therefore, we still have a lot to do and a long way to go.
