In 1900, the main causes of death were diseases that were spread by bacteria(细菌) and viruses(病毒).If you had lived then, the danger of your dying from pneumonia(肺炎) would have been three times greater than the danger of your dying from cancer.
The diseases that were most common in 1900 affected people of all ages. It is not surprising, then that around 1900, the emphasis of health was on freedom from illness. Today many of the diseases that were common in 1900 can be prevented or cured by improved medicines and methods of sanitation(卫生). Most diseases now are likely to occur later in life. You as a teenager will probably not have to think about the same threats to your health as your grandparents did.
These improvements in health conditions mean that not only can you now enjoy a better life, but you also have a greater chance of having a longer life. Conrtolling diseases has increased the life expectancy in the United States. Grenerally, people born more recently have higher life expectancies. Since 1900, the life expectancy in the United States has increased by more than 27 years. It has increased from 47 years for those born in 1900 to 74 years .

panic
A panic is a form. of collective in which a group of people, face with an immediate threat, re- act in an uncoordinated and irrational way. Their behawor is uncoordinated in the sense that co- operative social relationships and break down. It is irrational in the sense that people&39;s actions are not appropriate for the goals they wish to achieve.
The progress of a panic follows a fairly typical course. A sudden crisis occurs ; people experi- ence intense fear; normal social expectations are broken; each individual tries desperately to es- cape from the source of danger; mutual cooperation breaks down; and the situation becomes even more threatening as a result. Panics are especially likely to occur in unusual conditions in which everyday norms have little relevance, such as fires, floods, earthquakes or military invasions.
Some kind of response is necessary in these situations, but there are few social norms that specify an appropriate reaction. Thus, when a passenger aircraft makes a crash landing people may at- tempt to flee before fire breaks out and cause an explosion, but there only succeed in stopping themselves and others by creating bottlenecks at the exits. Awareness of bottlenecks, may lead to increased panic, with people fighting and trampling one another in the effort to escape. Despite intensive training of airline personnel in emergency evacuation procedures, a high proportion of passenger deaths are caused by a panic that prevents people from escaping in time.
The most dramatic panics are those that occur in situations of extreme emergency, but not all panics are quite so frantic or short-lived. A different form. of this collective behavior. is the finan- cial panic, which is typically provoked by rumor that the price of stocks will fall or that a bank will be unable to repay its depositors. The classic example, of course, occurred at the outset of the Great Depression in 1929: as in other forms of panic, the individuals involved tried to protect their own interests, and in so doing they worsened the situation for themselves and everyone else. By trying to sell their stocks as quickly as possible, people ensured that the price of stocks did fall; by demanding their money back from banks, they ensured that the banks actually did collapse.
