Medical sciences have made progress that the most optimistic scientists did not expect, and thanks to many recent discoveries, we no longer fear diseases that kill millions of people every year. Despite this, the progress that science has achieved in diagnostic methods and drug innovation has not benefited many patients as much as they expected. In most cases, the benefit was temporary, because they are not sick in their bodies as much as they are sick in their souls and nerves. The greatest enemy in our battle today against disease is the disturbed, rebellious nerves, and treating these nerves is in your hand alone. You may be born with delicate, sensitive nerves, but you are able to organize your life and practice habits that will give you peace of mind that will not spoil your health or disturb your life. You will be afflicted with illnesses that drugs cannot treat unless you take the initiative to change your lifestyle.
