By this point in our lives, we've been warned about the common problems that life can throw at us.
So we know to change the batteries in our smoke alarms, to look both ways before crossing the street, and to tell the bear with the hat that he can't have our "pic-a-nic" basket.
But some problems just come straight at you from your blind side. And even though I'm not a safety mascot, I should warn you about them.
