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

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

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

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.

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