My boss does crossword puzzles during staff meetings because it's easier for her to hear what people are saying when she's busy doing something fairly mindless.
I guess it's a tale of two coping mechanisms. Me, I generally just have to pop another meth-tab because the staff meetings fall right when my meds wear off, lol. Within 10 minutes I'm no longer fidgeting and can miraculously "hear" what people are saying. Also like the body relaxing. Nice. At least for those of us who don't find crossword puzzles relaxing, there's drugs.
