At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of   36 . They were able to show that we all have “a body clock”   37    us, which controls the   38   and fall of our body energies,   39   us different from one day to the next.

The   40   of “a body clock” should not be too   41   since the lives of most living things are controlled   42   the 24 hour night-and-day cycle. We feel   43   and fall asleep at night and become   44   and energetic during the day. If the 24 hour-cycle is   45   , most people experience unpleasant   46   . For example, people who are not   47   to working at night can find that   48   of sleep causes them to   49   badly at work.

  50   the daily cycle of sleeping and   51  , we also have other cycles which   52   longer than one day. Most of us would   53   that we feel good on some days and not so good on    54   ; sometimes our ideas seem to flow and at other times, they   55   do not exist.

In the early 1980s to have a mobile phone was an impossible luxury to most people in the world. People did not usually assume that they had to reach someone via a mobile phone on a regular basis. It didn’t matter if you didn’t have a mobile phone. In the modern society owning a mobile phone has no longer been a privilege, but a necessity. Almost anyone needs a mobile phone to reach as well as be reached by others no matter where they are. The days are gone when phone ownership depended on a fixed address and a high salary.   

It is amazing to see how fast and how far the mobile phone has spread. Teenagers have become the channel through which mobile phones have found their way into the wider society. The young were also the first to see the potential of text messaging. However, the mobile phone is by no means a mere technological innovation; it heightens a basic human quality ―the ability to communicate ―there are few aspects of life that it fails to touch.

The mobile phone is mobile only because the user is mobile. We are in a time of mobility. Never before have so many people been on the move, whether as commuters, workers, travelers, freelancers or migrants. Mobile phones encourage and respond to this mobility. They help those far away from their home to keep in touch with their families. They serve as a means of people fitting into a new social environment.

The mobile phone changes the way people organize their lives. Plans can be made or changed at any moment and while organizing in advance used to be extremely important to any social gathering, now only the vaguest plans are necessary. Mobile phones even change the experience of being alone as they provide countless way to pass the time.

It is ridiculous to compare a mobile to a body part, but carried on the person, often all the time, they are something to which people have grown attached.
