Did You Know?

From its literal Greek roots, atrophy would mean basically "lack of nourishment". Although the English word doesn't usually imply any lack of food, it always refers to a wasting away. Those who have been bedridden for a period of time will notice that their muscles have atrophied. And muscular atrophy is a frequent result of such diseases as cancer and AIDS. We also use atrophy in a much more general sense. After being out of work a few years, you may find your work skills have atrophied; someone who's been living an isolated life may discover the same thing about his or her social skills; and a democracy can atrophy when its citizens cease to pay attention to how they're being governed.
