Society has changed in many ways since the introduction of computers, and people's lives at home and at the office have been affected. Most people are working for fewer hours per week than they used to. Manufacturers and advertising agencies are becoming much more interested in how people spend this extra leisure time. One recent report stated that, although the number of hobbies had not increased, each hobby had become more specialized. A second finding is that nowadays, many managers would rather spend time with their families than stay late in the office every day. Home life is seen to be just as important as working. Some companies now make managers take their annual holidays even if they don't want to, because this leads to such an improvement in their performance if they have some rest. In spite of these changes, some people are working harder than ever before. The standard of exams is getting higher, and increased competition is making it harder to get into university than it was 20 years ago. School children and students are now having to work so hard that in many cases they work longer hours than their parents.
