"What causes unhappiness and illness? Toxins? I don't buy it."

Well you shouldn't by it either. Utilizing the precautionary principle, one would steer clear of toxins(talk-sins).

I went to a IAOMT dentist and had my fillings finally removed, and my temperament has improved. I get don't get angry to the same degree, or have the same level of anxiety, and my concentration is ever improving. While this has taken years to cleanse and rebuild the cells of my body, I know the result is mostly due to detox and a healthy lifestyle.

Getting fillings out is not spinning wheels, our body is constituted by vital minerals, Some of those directly affect our temperament. For example copper is critical for over all health, Having poor health will definitely contribute to unhappiness. Maintaining the proper supply of minerals to the cells in your body will in turn fortify your immunity and health. One good place to start is the Linus Pauling Institute.

Unfortunately minerals like mercury can help to create mineral imbalance, by affecting the digestive system. When that happens it can cause a cascade of illnesses and unhappiness. Temperament is the combination of mental, physical, and emotional traits of a person; natural predisposition.

That predisposition is directly affected by the mineral content of a person. Just as a metal cutting instrument(like a sword) has a temper due to the minerals it consists of, so to do the cells in the body have a temper and conductivity that functions on the basis of their components.
