in
which
two
people
are
discussing
what
the
human
body
and
mind
are
capable
of
doing.
Underline
the

Now,
you
have
five
minutes
to

the

are
capable
of
doing.
You

Human
body
is
capable

doing
many
things,
such

I
really
admire
people
who
use
their
minds
for
the
betterment
of
mankind.
For
example,
physicists
discover
the
unknown
world
and
the
universe;
and
information
technologists
create
robots
to
do
the
work
for
human
beings.
Now,
let’s
move

After
listening,
you
are
supposed

It
is
health
that
is
real
wealth
and
not
pieces
of
gold
and
silver.
—Mahatma
Gandhi
It
means
there
are
other
things
more
important
than
money.
For
example,
your
body
is
important
and
not
the
pieces
of
metal.
I
totally
agree
with
this
quote.
Compared
with
gold
and
silver,
our
health
matters
more
to
us.
Without
health,
we
have
nothing.
So
we
should
maintain
a
healthy
lifestyle.
