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

The idea of "a body clock" should not be too  38   since the lives of most living things are controlled by the 24 hour night-and-day cycle. We feel  39   and fall asleep at night and become  40  and energetic during the day. If the 24 hour-cycle is disturbed, most people experience unpleasant  41   . For example, people who are not  42   to working at night can find that  43   of sleep causes them to  44   badly at work.  45  the daily cycle of sleeping and waking, we also have other cycles which last longer than one day. Most of us would  46    that we feel good on some days and not so good on others ; sometimes our ideas seem to flow and at other times, they  47  do not exist.
