Practicing regular, mindful breathing can be calming and energizing and can even help with stress-related health problems ranging from panic attacks to digestive disorders.
I tried to change the conventional paradigm, for example, by insisting on the reality of mind-body interaction, by stressing the importance of natural therapies, by focusing attention on lifestyle issues, by looking at worthwhile aspects of alternative medicine. Many people have been threatened by that. Doctors especially tend to think that they know everything about the human body, and don't realize that medical education has really omitted many very important subjects.
I think it's worth trying to do something about obvious sources of stress in your life. But even more important is learning and practicing methods to neutralize the harmful effects of stress on the body and mind. There are many possibilities, anything from meditation and yoga to listening to relaxing music. My personal favorite is simple breathing techniques - they're very effective, take very little time, and they're free.
I don't think you can live without stress; I think the human life is stressful, and it probably always has been, although the forms of stress may change from culture to culture, and from time to time.
