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.

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.

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

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.
