6. As long as your municipal water supply is
free of lead, you don't need to worry about
6. lead in your tap
water.
Answer: B.
Though your municipal water supply may be free of lead, it
can enter your
tap water through aging pipes in older
homes (generally those built before 1986).
If you're
concerned about lead in your home water, have the water
tested. There are a
number of water treatment options,
including some filter pitchers, to reduce
lead.
Additionally, you can minimize your exposure to
lead by running the water from your
tap until it's as
cold as possible before drinking it (especially first thing
in the morning),
and by using only cold water for cooking
and drinking (hot water can draw more lead
from the
plumbing.

7. It doesn't matter whether you drink your
total day's intake of water in one sitting or
7. throughout the day;
as long as you're downing your daily dose, you'll enjoy all
of
7. water's
health benefits.
Answer: B.
When we drink large quantities of water at one time, we
stimulate the
body to rid itself of water, according to
fitness expert Bob Greene. That's why it is
important to
drink water throughout the day and not just all in one
sitting. And, not just
when you're thirsty. In fact, by
the time you feel the sensation of thirst, you
body
already may have lost one to two percent of it's
water, propelling it into
dehydration.

dehydrated if they're not careful because early
symptoms
are easily missed. |
