We
all
know
that
many
students
often
go
online
but
we
were
surprised
that
ninety
percent
of
them
use
the
Internet
every
day.
The
other
ten
percent
use
it
at
least
three
or
four
times
a

Most
students
use
it
for

not

It’s
good
to
relax
by
using
the
Internet
or
watching
game
shows,
but
we
think
the
best
way
to
relax
is
through
exercise.
It
is
healthy
for
the

Exercise
such
as
playing
sports
is
fun,
and
you
can
spend
time
with
your
friends
and
family
as
you
play
together.
And
remember,
“old
habits
die
hard.”
So
start
exercising
before
it’s
too
late.
