My focus is on "the brain in the body." The brain is the center of our entire physical world, it is where we think, feel, see, and perceive. Most people want to sell products that help the brain, but don't understand why they are selling such a useless product. This is where the brainpower in the body comes from. If the body cannot grow beyond a certain point, a problem will arise. For example, if your brain is 80% of your body, then your muscles will have a hard time getting your body to grow beyond this level. So, we all have some brainpower in the body, even if we don't want to admit it. In the beginning, it's hard for me to understand what the point of a lot of this brainpower is. Some people have tried to make money from this brainpower, but failed. What are these people doing? If they were doing this for a purpose, then I would applaud them.
However, I have a much better understanding. The point of all this brainpower is not that people will gain a huge amount of brain power; it's simply to enhance the brainpower of those who already have it.
