The brain is a good thing. The more you use it, the better it becomes. Do we often hear such words around us? So here comes the question, what kind of state is the brain in for processing and use, and what kind of state is it so that it won’t get rusty? Let’s talk with you about using your brain.

Personally, I think that the use of the brain is what we call brain use in layman’s terms. There is no specific quantitative number on how to use the brain scientifically and effectively, but we can use the behavior under the command of the brain to judge the use of the brain. I think brain use can be mainly divided into active brain use state and passive brain use state.

Actively using your brain is a positive way of thinking. It is a process that requires investment of energy and time, and the brain works rapidly. Our daily thinking about problems, solving problems, composing an article, and writing a plan can all be classified as active. The main feature is that it requires full devotion and the use of all the senses to deal with this matter. The word "brain-burning" can vividly illustrate this behavior, which is a very strenuous way. Being in this state for a long time will make people greatly exhausted. But the effect presented in this way is obvious, and it is also a very useful behavior.

The opposite of actively using your brain is the passive way of thinking. This is the same way of thinking, but it is weakened in degree and has lower requirements in all aspects. It's a feeling of being pushed along. I will use the example of ship driving on large rivers and oceans to illustrate this state. When sailing in complex stretches of inland rivers, ship driving is usually completed by two people working together, one to pilot and one to steer. Here the pilot is thinking actively, while the helmsman is a typical passive thinking method, because he only needs to obey the pilot's instructions to steer and does not show his own navigation intention.

I think it is an exaggeration to say that the brain will rust if not used, and this is unlikely to exist in reality. However, if people often do not pay attention to active thinking and training, most people's thinking ability, reaction ability, etc. will become slow.
