Crisis "Crisis!" As a society, any time, as a society, we listen to the words, our ears cheer up and speakers draw our attention. Normally, when we hear the crisis, we believe this is "a clear possibility of a very undesirable outcome" (Merriam Webster) and we need to respond immediately. President George W. Bush said we are in a nationwide "energy crisis" (Iska Nevada is a safe disposal place?). President Bush proposed a solution to store all of the nuclear waste of our country in Yucca Mountain, Nevada, but it was strongly resisted by Nevada residents, politicians and environmental protection groups.
The crisis is an unplanned, unwelcome, dangerous event that can lead to difficult decisions. There are various kinds of crises such as economic crisis, mental health crisis, situation crisis, social crisis, and occasional crisis. The impact of each kind of crisis on people exceeds our thoughts and understandings. There will always be people who fail due to the crisis and are paid for salary. - Microglia is a hematopoietic-derived innate immune cell that constantly investigates the environment and regulates the development of the central nervous system (CNS). These cells have a dynamic cellular process that comes into contact with synapses from dying neurons and cell pieces of phagocytic cells. The origin of microglia is a controversial topic for decades.
The concept of "crisis" here is the core and must be taken seriously. The crisis is not just a "challenge", it is not just a "rough place". We are on the verge of crisis everywhere. We are in danger of personal life, interpersonal relationship, work, economy, science, political revolution. The meaning of the crisis can be briefly stated: "The crisis is the process of change, the old system can not be maintained." This is a deep understanding, it brings clarity. The crisis is the threshold between the old system and the new system. From the perspective of the old system, the crisis is death. This is the reason why older systems always try to avoid the crisis like hell. I do not want to be rude here. The system is difficult to run - leaving old systems on new, untested, untested systems is almost always a really scary idea. Even if some new systems are implemented, the migration itself is inevitable and it will often be fatal.
