I will also give different explanations according to the different people I face. Or this is a psychological therapy technique that works from the physiological level; Or it can be used to solve learning difficulties and let us learn faster and better; Or to reshape the brain and make us smarter. Usually after I finish writing, the feedback is: "Oh, so that's it!" " "Seems to understand what, still feel very confused. In fact, this feeling often appears on me. I came into contact with brain-strengthening exercise in August 2005. At that time, I learned a trick and a half. After practicing, I think it is really helpful to enhance my reaction. At that time, the understanding of brain-strengthening exercise was limited to these movements. A few months later, I accidentally turned to this book and stumbled upon the words "brain exercises". I think this concept is still a mess for me, so I decided to take some time to understand it thoroughly. Then I went online and read hundreds of explanations about "brain exercises" with a search engine. I just know that "mental exercise" is a science that has been brewed by an American educator for many years and created by combining various technologies. Then, I wrote to my nearest teacher to learn more about brain exercise. The email has been sent for three months, and I feel that Brain Exercise is still a lingering fog for me. " It's hard for me to understand what I got on the paper. I never knew it had to be done. "Finally, in March this year, I went to Hong Kong to verify this matter. After staying in Hong Kong for six days and seven nights, I discovered a vast world of human kinematics. My understanding of brain exercises is a series of interesting and powerful exercises, a set of skills to develop whole brain learning, and a unique methodology to integrate brain organization with body and mind. At the same time, I also have more concepts that I don't understand, don't understand and don't know. What "harmony", "remodeling", "muscle energy detection" and so on. This has fulfilled an old saying, "The more you know, the more you don't know". "So far, I have read more than 20 books about brain-building exercises, participated in more than 60 hours of brain-building exercises, and introduced brain-building exercises to hundreds of people. However, I am responsible to tell you that I don't know what brain health is yet. I can't convey my feelings to you, nor can I make you feel my feelings. What I know is that brain-strengthening exercise has been integrated into my life, into my life. It surprises me every day and makes me change! I don't know what it is, it has become a part of me. If you ask me what is mental exercise now? Let me tell you something. You'll know when you learn. Nevertheless, in order to make friends who read this short article not feel a little depressed, I quoted some explanations in the book. " Mental exercise is a group of interesting physical exercises. ""Brain exercise is a set of tools to eliminate learning disabilities and behavioral disorders. " "Brain-strengthening exercise is knowledge created by combining the theories and skills of kinematics, developmental physiology, neurolinguistics (NLP), medicine and psychology." "Brain-strengthening movement thinks that learning is a natural, interesting and lifelong activity." "Brain exercise is a unique program and method, which can reshape the operation mode of our brain, make us study easier, work happier and live happier. "... there are more explanations that cannot be listed one by one. As the saying goes, "the deep see the deep, the shallow see the shallow". Different people have different understandings and understandings of brain-strengthening sports, so they will have different judgments and choices. No two people in the world have exactly the same knowledge and understanding of a thing, which is the uniqueness of our human beings. I respect the existence of this uniqueness. Therefore, it may be better to leave the question of "what is mental exercise" to yourself to explore.
