Office buildings are chock full of all sorts of toxic stuff. Toss in all the computers and other items that would have been in a building that size and you have a lot of toxic soup. The office building I worked in in Hollywood had a warning label in the main lobby about the toxic stuff in it.
Offices everywhere are chock full of comfort, productivity, and contentment.
Until a forceful change is brought about by fanatics....
Lest we forget.
