In 50 years many diseases will be cured through medical technology. Today, there are electronic devices that can help people hear. In 50 years, doctors will be able to help blind and deaf people to see and hear again, and new medicine will enable people to live longer. What’s more, scientists will discover how to control genes. Now clones of animals have already been produced by scientists. Some scientists are even planning to clone people, and decide how they look, how they behave and how intelligent they are.
