WHAT YOU DON'T KNOW
They say, "What you don't know can't hurt you." But it's not true, is it?
Suppose your house is invaded by termites that are eating away at the studs and beams and rafters, and you don't know it.
Suppose you are on an extended trip but you left water boiling on the stove--and you've forgotten it.
Suppose you have an allergy to some food you love, but you've never made the connection.
Suppose you are at a party with strangers and you have a piece of food on your teeth--only you don't know it.
Not knowing what you need to know can, in fact, hurt you.
