The doctor is so pitiful that he prescribes a lot of useless drugs every time, and it has no effect at all. Last time I told him not to prescribe useless medicine, as a result, he insisted on avoiding the reason and prescribed it again. Hello, happy Mid-Autumn Festival. The body is your own, and the doctor is a doctor. I know better than the doctor what's wrong with my body. So the best doctor is himself, without studying medicine. It is too late to start learning health knowledge at any time. Doctors are not omnipotent. If you have this interest, it is not too late to start studying now. Many health masters began to ponder and study because of physical problems. The important thing is to study persistently.
