Scientists find that hard-working people live longer than average men and women. Career women are healthier than housewives. Evidence shows that the jobless are in poorer health than jobholders. An investigation shows that whenever the unemployment rate increases by 1%, the death rate increases by 2%. All this comes down to one point: work is helpful to health.

Why is work good for health？ It is because work keeps people busy away from loneliness. Researches show that people feel unhappy, worried and lonely when they have nothing to do. Instead, the happiest are those who are busy. (76) Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a bridge between man and reality. By work people come into with each other. By collective activity they find friendship and warmth. This is helpful to health. The loss of work means the loss of everything. It affects man spiritually and makes him ill.

Besides, work gives one a sense of fulfillment and a sense of achievement. Work makes one feel his value and status in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond words.

(77) From the above we can come to the conclusion that the more you work the happier and healthier you will be. Let us work hard and study and live a happy and healthy life.
