For example, when we perceive our health in a positive way; we are more optimistic about our health, compared to patients who went into surgery with a negative attitude. When patients describe their health as poor, they are almost 3x's more likely to die of any cause. (Reference: Daniel. Mark, M.D., Duke University School of Medicine)
Our brain registers optimism in a positive way and adjusts the chemical and neural pathways that affect cellular function throughout our body. Visualization (creating positive mental images) can boost our immune system and cancer patients who have practiced guided imagery for eight weeks [Journal of Personal Social Psychology, 1998; Vol.74, pp. 1646-1655] increased the count of Cancer-fighting cells which reject tumors.

Res, 2002, Vol.53, pp. 1131-1137]
