Reading in dim light will
harm your eyes.
Myth! It might tire your eyes in the
short term, but there’s no evidence
that it will do any lasting damage.
When reading, position light to shine
directly on the page rather than from
over your shoulder to reduce glare.22
Coughing too much
can make you throw up.
Truth! Little kids are especially
prone to vomiting after coughing fits
because their gag reflexes are extra
sensitive, but it can also happen to
adults. It usually isn’t a big deal, but
if you keep puking, see a doctor.20
Eggs are bad for your heart.
Myth! The old thinking was that cholesterol in food would raise blood
cholesterol levels and in turn increase the risk of heart disease. A recent study
of more than 400,000 adults found that eating an egg a day increased good
cholesterol and cut the risk of cardiovascular death by 18 percent.72 march 2019
