What does human being need????

What does human being need? We do not know, A hundred years ago people did not know that one of the most important human needs was protection against disease- causing germs. There are probably needs as important as this which we do not yet know, but people will know a hundred years hence. We can still make a list, even if we are sure that something important might have been left out. First on our list will be the most urgent needs without which anyone would soon die. And later on we shall list some of the things we need if we are to be happy and things which will be useful (for example learning to communicate in English effectively) though we do not need them for life or even for health.

          When I made a list, I soon found out that most of our needs are quantitative. We must not have too little of various things but we also must not have too much. We need some food, but too much of even the best food makes us sick. We need education if we are to fit into a civilized society, but a boy who was made to read for twelve hours a day might not fit in very well. Different people have different needs according to their age, sex, job and so on. Finally, a lot of what we think we need is needlessly acquired. If we have been accustomed to something, such as chocolates, TV or smartphone, we may get unhappy if it is taken away, but we could have got on all right without them.
