This is because when faced with a dangerous dilemma, our human brain is first triggered by the primitive brain, which will immediately start the "fight/flight" mode. Before the rational brain in the cerebral cortex receives the information, the body has already started to act according to its own ideas. So don't always think that the brain is controlling the body. In the face of danger, your soul can't keep up with your body.
However, we are faced with the complicated situation that women are molested in the subway. For example, we are not sure that molesters may be not only obscene but also cruel. At this time, you need to calm yourself down and let the rational brain start analyzing the work. Maybe you think it's time to calm down and waste your time. What if that pervert doesn't molest people? In fact, our brains are very fast. This cooling time is only one or two seconds, and a multi-thread prediction scheme will be given between cracks. Of course, wisdom comes from the accumulation of life experience and continuous learning. Most of us don't have much life experience in the face of "Zhang San", so we should consciously simulate all kinds of difficulties and dangers in our minds, practice thinking strategies and improve our ability to solve problems.
