Lipitor is one of the most researched medicines. I'm glad I take Lipitor, as a doctor, and a dad.

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.

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 am a medical scientist, not a practical physician.

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