An eighty-year-old lady walked into a physiotherapy clinic and said to the doctor; Doctor, I have difficulty falling asleep recently, and I can’t sleep at 12 o’clock at night! The doctor recommended a course of foot therapy for her to clear the meridians, improve microcirculation, and ensure that the old lady eats well and can sleep well. The old lady was too overjoyed and thought it would make people enjoy it—magical. The old lady asked the doctor how much is a course of treatment? The doctor said; ten thousand. Watering the flowers and roots, the treatment must start from the feet. The old lady did a course of foot therapy but no results. Ask the doctor what to do? The doctor recommended hand therapy for her. The old lady asked how much is a course of treatment? The doctor said ten thousand, fingers are connected to the heart, and hand therapy is definitely right. The old lady did a course of hand therapy, but it still didn’t work. Ask the doctor what to do? The doctor recommended head treatment for her. The old lady asked how much is a course of treatment? The doctor said ten thousand, everything is difficult at the beginning. It seems that your illness is in your head. If you solve the initial problem, the illness will be cured. The old lady had another course of head treatment. She couldn’t sleep even after 12 o’clock at night, and turned into insomnia all night. The old lady was in a hurry and asked the doctor what to do? The doctor said: Do it again, the same as before, but you have to take it again. The old lady said distressedly; if I spend 30,000 yuan to do it again, another person in my family will have trouble falling asleep! Who is the doctor asking? The old lady said; my eighty-year-old wife!
