[Callers] Another occupational hazard for callers

You might also consider how to make a test as to whether there is UV in 
your environment.
I did a little research and turns out there is a little trick you can 
perform.
Highlighter markers rely on UV to make them glow.
So if you use one to write on a dark or preferably black piece of cardboard,
under non-UV you can't see anything, but under UV the lettering glows.
It would be nice to know how good a test this is under real conditions.
Maybe you want to put one in your deck of cards.
