There is a clear matter that I am not a practicing physician; I have never been a practitioner; everybody has known for decades.

As a medical doctor who chose a career in artificial heart technology rather than clinical practice, I decided not to take an internship, which is required for licensing. Instead, I work with invention, manufacturing, regulatory affairs, and clinical application of artificial hearts.

As spokesman for Lipitor, I have been an advocate of preventive medicine in addition to my work with the Jarvik 2000 Heart, which has rescued people from death and sustained a patient with a normal, mobile lifestyle for seven and a half years - the longest in the world.

I do not practice clinical medicine and hence do not treat individual patients. My career is in medical science.

This idea that clumsy, stumbling people are real bright is ridiculous, because intelligence is related to neurologic function, and really intelligent people are very well-coordinated.

The artificial heart is very effective as a bridge to transplant, but the number of people that can be saved with human hearts is limited. A perfect artificial heart could save many more patients.
