Do you think scientists will produce a mechanical heart one day that will be able to work forever?

I strongly believe that scientists will invent a mechanical heart that will be able to work forever. There is nothing that people can\'t do. We have a lot of experience that impossible things happened as time went by. For example, we didn\'t expect that we would use a mobile phone and smart phone. However, engineer and inventor finally showed the new technology for customers. As I know, many doctors and scientists have studied about a artificial heart and have published their research results. We can easily meet the patient who has a cardiac pacemaker. I think that It\'s a kind of mechanical heart. If it will happen, a lot of patients can be treated. However, researchers must have a lot of trials to animals before they implement a mechanical heart to the public. I hope that nobody have a serious disease and can be treated by new treatment.
