Slice reader Jim Bohn passed along a cautionary note.
"It's that time of year again when we are all facing many hazards associated with the year-end holidays. Driving in inclement weather, climbing ladders to string lights, overloaded electrical circuits, shopping, and eating fruitcake.
"A little known but insidiously dangerous additional hazard is the innocent looking glitter-covered greeting card. Fine glitter spews forth when the cards are pulled from the envelope, going airborne. It resists containment and cleanup. Chronic exposure can result in debilitating 'glitter lung' (no kidding, look it up).
"At our home, each incoming greeting card is carefully screened for glitter and those suspected of being glitter containing are carefully opened in a special containment area, and then incinerated at 1200 F. You should warn the public, and urge that the use of glitter be discouraged and eventually eliminated."
