How do you react when someone is rude to you? Reaction is the key word here. You cannot control the events or circumstances of your life, but you can control your reactions. Controlling those reactions is the difference between healthy minds and bodies and sick minds and bodies.
Here are just a few statistics confirming that 75 to 98 percent of mental and physical illness comes from one’s thought life:
A study by the American Medical Association found that stress is a factor in 75 percent of all illnesses and diseases that people suffer from today. The association between stress and disease is at an astounding, 85 percent.
According to Dr. Bruce Lipton, a scientist who has made great strides in understanding the effect of our thinking on our brain, gene disorders affect less than 2 percent of the population. 
This means the vast majority of the world’s population comes into this world with genes that should enable them to live happy and healthy lives. Lipton says that 98 percent of diseases are related to lifestyle choices – in other words, our thinking. According to Dr. H. F. Nijhout,  genes control biology and not the other way around.
According to W. C. Willett,  only 5 percent of cancer and cardiovascular patients can attribute their disease to hereditary factors.
The American Institute of Health estimates that 75–90 percent of all visits to primary care physicians are for stress-related problems.  It is really eye-opening that some of the latest negative stress statistics causing sickness are a result of toxic thinking.
