The body will heal itself," says Ellen Heber-Katz, professor of oncology at the Wistar Institute in Philadelphia, USA. "I believe that in the near future, we will be able to prescribe drugs to patients that will allow the heart to regenerate itself after a heart attack, 
the spinal cord to heal from damage sustained in a car accident, and limbs lost in a car accident to regrow. Diseased or malfunctioning organs will be repairable just as we do with cars today—by replacing faulty parts with new ones, preferably manufactured by an authorized manufacturer. Great advances in heart regeneration are just around the corner; in five or 10 years, we will learn to stimulate the body to regrow fingers, and a few years later, entire limbs. As for the nervous system, we will first learn to force the retina and optic nerve to repair themselves, allowing patients to regain their sight. Then we will be able to do the same with the spinal cord, which in turn will help people suffering from paralysis." In 50 years, replacing all body parts with new ones will be commonplace.
