I am a medical scientist, not a practical physician. I think it's very upfront. I am a doctor. I have long experience with heart disease.

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

I am a medical scientist, not a practical physician.

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.

The United States has an active pharmaceutical industry that has brought huge benefits to the U.S. public. Most Americans, who benefit from these advances, have little understanding of how difficult it is to create an important new medical therapy and make it available to improve public health.

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