Once when I was nine, I came down with a horrible case of tonsillitis (扁桃腺炎). I remember going to the doctor, feeling miserable and scared, but also knowing that this man would somehow fix me. As he declared his conclusion regarding my illness, he asked my mother “Is your daughter allergic (过敏的) to any medicine? ” My mom hesitated for a moment, while I was looking at her questioningly. Was I allergic to anything? What if I was? What would happen to me?  My mother said no.
That evening after taking my pill, I began to shake uncontrollably. I complained of a terrible headache and continued shaking as my mother held me. She didn’t seem very concerned, yet I believed I was allergic to the pill. Before I fell asleep that night, I told my mom the medicine had made me sick and I wouldn’t take it anymore. The next morning, my mother had me drink a tall glass of iced tea that tasted funny. Later that afternoon, my mom asked me how I felt. I told her I was doing much better, and that was when she dropped the bomb on me. She told me she had mixed my ice tea that morning with my medicine. Guess what, no allergic reaction. I was never allergic to the pills, but my powerful subconscious (潜意识的) mind, accepted a mere suggestion by the doctor that I might be, and my body acted accordingly.
Most of us have no idea how powerful our minds are, and how incoming information continually affects our experience. When I took that pill, it had a negative effect on my mind. Researchers are finding more and more evidence that what we believe, or expect to happen medically, has a deep effect on what actually does happen. 
In some medical trials, the patients never took any medicine, only sugar pills, but were told they had been given expensive medicine, and their conditions improved anyway. They simply believed they would get better. On the other side of the coin, people who believe they are going to die in an operation have a higher death rate than people who don’t.
What we expect often tends to get realized. The power of your mind to heal your body is absolutely fantastic.  Take care in what information you choose to believe about your health and well-being. Think positively about your outcome in medical situations and allow your power of belief to help you heal.
