When we work-and also when we play-we use up energy,the energy may be physical or mental or a compination of the two.When our work or play is prolonged,we become tired and want to stopand rest or changeto some other activity.If we do not stop,we become gradually less efficient.If we set someone at a job and keep him at it continuously without rest,ultimately he uill break down and be uneble to go on.
If rest intervals or changes of activity are introduced,the person uill be able to work for a much longer period of time.
Efficiency,then,seems to be mainly a metter of the distribution of work and rest periods.In ordinary life.We work during the day and sleep at night,year in and year.

Organication also makes a difference in our ability to remember.How useful would a library be if the books were kept in random order?Material that is organized is better remembered than jumbled information.One example of organization is chunking.
Chunking consists of grouping separate bits of information.For example the number 4671363 is more easily remembered if it is chunked as 467,13,63.Categorizing is another means of organization.Suppose you are asked to remember the following list of works,man,bench,dog,desk,woman,horse,child,cat,chair.Many people uill group the words into similar categories and remember them as follows:man woman child;cat dog horse；bench,chair,desk.
Needless to say,the second list can be remember more easily then the first one.

Many of the plants and animals from which our food comes can produce themselves quite well without our help.Fish,for example,live and bread according to their own life pattern!Human “producers” then come with nets and fishing poles to take the fish from the water.
In our specialized world,however,it is not always possible to let our food grow in its own way.A relatively small number of people are responsible for producing large quantities of food.In order to perform such a function effectively.It is necessary for them to raise cattle and grow crops in a fairly concentrated area Fishing,livestock breading,and fruit vegetable,and grain growing are among the more commonly known food producting industries.
