After a busy day of work
and play, the body needs to rest. Sleep is
necessary for good
health. During this
time, the body recovers from the activities of the
previous day. The
rest that you get
while sleeping enables your body to prepare itself
for the next day.
There are four levels
of sleep, each being a little deeper than the one
before. As you
sleep, your muscles
relax little by little. Your heart beats more
slowly, and your brain
slows down.
After you reach the fourth level, your body shifts
back and forth from one
level of sleep
to the other.
Although
your
mind
slows
down,
from
time
to
time
you
will
dream.
Scientists
who
study
sleep
state that when dreaming occurs, your
eyeballs begin to move more quickly (although
your
eyelids
are
closed).
This
stage
of
sleep
is
called
REM,
which
stands
for
rapid
eye
movement.
If you have
trouble falling asleep, some people recommend
breathing very slowly and very
deeply.
Other people believe that drinking warm milk will
help make you drowsy. There is
also an
old suggestion that counting sheep will put you to
sleep!

To the curious
and the courageous, the sea still presents the
challenge of the unknown,
for ignorance
is still the distinguishing characteristic of
man's relation to the sea.
But now,
more than ever, necessity urges us onward in our
exploration of the sea. We now
have
submarines capable of staying under water of many
months holding missiles capable
of
destruction
many
times
greater
than
those
used
in
World
War
II.
For
strategic
reasons,
therefore, we need
urgently to learn more about the ocean bottom.
Quite apart from the
threat of war,
another necessity presses us to learn to master
the sea. That necessity
is basic to
life itself: food. The lives of two-third of the
world's people are wholly
dictated by
that basic necessity, they are oppressed by hunger
and by the weakness and
disease
which
hunger
generates.
Out
of
the
sea
we
can
extract
the
food
to
relieve
the
hunger
of
these
millions
of
people
and
give
dignity
to
their
lives.
We
must
turn
to
the
sea,
because
the
bounty of the land has limit.

It is a matter of
common observation that although incomes keep
going up over the years,
people
never
seem
to
become
much
better
off!
Prices
are
rising
continuously.
This
condition
is termed one of
inflation; the money supply is becoming inflated
so that each unit of
it
becomes
less
valuable.
People
have
grown
accustomed
in
recent
years
to
higher
and
