The bottom line is that the human body is complex and subtle, and oversimplifying - as common sense sometimes impels us to do - can be hazardous to your health.

Routines may include taking a warm bath or a relaxing walk in the evening, or practicing meditation/relaxation exercises. Psychologically, the completion of such a practice tells your mind and body that the day's work is over and you are free to relax and sleep.

I think integrative medicine, something I've pioneered, is the way of the future. Its great promise is that it can reduce healthcare costs by shifting the whole focus of healthcare away from disease management to health promotion and prevention. They can do that two ways: first, by focusing attention on lifestyle medicine, which is very deficient. And second, by bringing into the mainstream treatments that are lower cost because they are not dependent on expensive technology.

Drugs don't have spiritual potential, human beings have spiritual potential. And it may be that we need techniques to move us in that direction, and the use of psychoactive drugs clearly is one path that has helped many people.

The underlying idea is that you can prevent disease by balancing your body's pH... None of these claims are true. Furthermore, your body needs absolutely no help in adjusting its pH. Normally, the pH of blood and most body fluids is near seven, which is close to neutral. This is under very tight biological control because all of the chemical reactions that maintain life depend on it. Unless you have serious respiratory or kidney problems, body pH will remain in balance no matter what you eat or drink.
