graduates express their gratitude to their school teachers in three different ways. To begin with, every holiday season they remember to send them beautiful cards, or gifts of flowers. Second, time and time again, they invite their teachers out to dinner in fine restaurants, sharing them with their own affairs.

For a large number of people, the absence of work is harmful to their health. Retirement often brings many problems surrounding the “What do I do with myself today?” question, even though there may be no financial cares. Large numbers of people regularly get headaches and other illnesses on weekends when they don’t have their jobs to go to, and must fend for themselves. It has been observed that unemployment, quite aside from exerting financial pressures, brings enormous psychological troubles and that many individuals deteriorate rapidly when jobless.
Because
of modern technology, humans will be better off economically 20 years from now than they are today. Hundreds of millions of people will live in homes that will seem like palaces to their parents and grandparents. At the same time. Brought together by telecommunications, people around the world will work together more efficiently than ever before. Expertise will flow easily and cheaply to places where it is needed. Computers and cellular phones will become commonplaces.
