Love and intimacy are at the root of what makes us sick and what makes us well...I am not aware of any other factor in medicine-not diet, not smoking, not exercise-that has a greater impact.

People who are lonely and depressed are three to 10 times more likely to get sick and die prematurely than those who have a strong sense of love and community. I don’t know any other single factor that affects our health - for better and for worse - to such a strong degree.

I don't understand why asking people to eat a well-balanced vegetarian diet is considered drastic, while it is medically conservative to cut people open and put them on cholesterol lowering drugs for the rest of their lives.

I usually find that the process of discovery is more interesting than the answers.

Although scientists can often be as resistant to new ideas as anyone, the process of science ensures that, over time, good ideas and theories prevail.

I am as non-accepting of medical quackery and unscientific approaches as anybody else. I've grown up as a card-carrying scientist, and I know the power of science to answer questions, and for many questions I don't know of anything better than scientific approaches to answer them.

Poor health is not caused by something you don't have; it's caused by disturbing something that you already have. Health is not something you need to get, it's something you have already if you don't disturb it.
