For Janet it’s all about the puzzle, the clue, the problem to be solved. Word games are her favorites. Crossword puzzles, Words With Friends, she loves them all. She even finds time for KenKen (proper name KenDoku). The harder she has to work, the happier she is. You’d think her hobby would fill her with an elevated sense of self worth. The truth is that she feels hopelessly under the sway of what she thinks of as her addiction. True, her memory is as sharp as a tack. But that’s cold comfort when she weighs it against the sorry state of her knees.
