I am, in fact, a medical doctor; I am a world expert in mechanical heart technology; and I am an athletically fit man who takes care of his own health through diet and exercise, including frequent five mile runs.

I knew that my father was going to die of heart disease, and I was trying to make a heart for him.

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.

Leaders are visionaries with a poorly developed sense of fear and no concept of the odds against them.

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.

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.
