As a doctor, it is sometimes difficult because patients want their symptoms gone - fast. Symptoms interrupt the patient's life. By the time a symptom is consistent enough to no longer be ignored, a patient has often lost 60% or greater function.

Vitalistic strategies recognize stress literally breaks our body's healing power. Functional strategies attempt to strengthen the body's ability to adapt to this stress.
