I think that in 21 the tissue engineering will develop. By 2040 major neo-organs such as the heart and lungs will be generated from cells. Scientists have already been successful in growing skin, pieces of bone. The fully replacement for such body parts as hands and ears will be available by 2025. Inherited diseases may be successfully combated by gene therapy. Gene therapy is a new form of treatment that involves the insertion of a healthy gene into a virus that has been neutralized so that it can do no harm. the modified virus, carrying the corrected gene, is then injected into the patient. Soon I think that cash will disappear. In 21 century e-cash will be accepted even in the most remote corners of the planet. In future doctors will be able to tailor specific drugs for individual patients. This will help to increase the effectiveness of the treatment many times.

I believe that in the 21st century the development of the tissue engineering will be increased.

By 2040, heart and lungs can be generated from cells. Already now, scientists had successful experiment on skin and bone tissues' re-generation.

After that, the modified virus, carrying the corrected gene, is injected into the patient.

As far as economy, I think that cash will not be used anymore.

remote corners of the planet - in the most undeveloped countries....?
