I understood Bruce Lipton as saying that not only DNA and the environment influence us, but more significant is our attitude.  What we think, believe, feel and expect are significant factors in our life experience, but also influence our physical and mental state of welllbeing. 

This is now labelled as psychsomatic medicine, but it seems to have failed to put the power back in the hands of the patient.  Rather the drug pushers have used it as an opportunity to label thoughts as mental illness and find dugs to change them.
