There
is
an
old
English
saying,
“Laughter
is
the
best
medicine.”
Norman
Cousins
was
the
person
who
agreed
with
this.
Norman
Cousins
was
the
editor
of
a
magazine
for
almost
forty
years.
He
also
wrote
and
spoke
about
world
peace,
traveling
to
many
different
countries
to
29．.
In
the
1960s,
after
returning
to
the
United
States
from
a
busy
and
tiring
trip
to
Europe,
Mr.
Cousins
30．.
He
discovered
he
had
a
rare
disease（罕见的疾病）.
In
less
than
a
week
after
he
got
back,
he
could
not
stand.
Every
move
that
he
made
was
painful.
He
was
not
able
to
31．.
The
doctors
told
Mr.
Cousins
that
they
did
not
know
how
to
cure
his
problem
and
he
might
never
get
over
the
illness.
Mr.
Cousins,
however,
refused
to
32．.
Mr.
Cousins
thought
that
the
illness
could
be
caused
by
33．.
He
did
not
want
to
take
medicine
to
cure
himself.
Instead,
he
felt
that
34．
or
laughter
might
cure
his
illness.
He
began
to
try
on
himself
while
still
in
the
hospital
by
35．
on
television.
Mr.
Cousins
quickly
found
that
ten
minutes
of
real
laughter
during
the
day
gave
him
two
hours
of
pain-free
sleep
at
night.
Deciding
that
the
doctors
could
not
help
him,
Mr.
Cousins
left
the
hospital
but
he
continued
his
experiments
with
36．.
For
eight
days,
Mr.
Cousins
rested
in
the
hotel
room
watching
comedy
shows
on
television,
reading
funny
books,
and
sleeping
whenever
he
felt
tired.
Within
three
weeks,
he
felt
37．
to
take
a
vacation
to
Puerto
Rico
where
he
began
running
on
the
beach
for
exercise.
After
a
few
months,
Mr.
Cousins
was
able
to
carry
on
his
work.
He
had
laughed
himself
back
to
38．.

given
by

read
many
classical
novels.

I

to
stay
healthy.
Besides,
I
paid
close
attention
to
the

Internet.
What
moved
me
most

nurses.
They
are
real
heroes
and
I've
made
up
my

to
learn
from
