Darn, I wish I could only imagine it. I think some do it for obvious reasons: to avoid work or a touch of agoraphobia, and don't want to go out. I agree some probably do it for attention. They may be a hypochondriac. People should be careful about this for the same reason as the little boy who cried wolf. One day, they may get sick and be brushed aside. My question is, why do most people do anything? It isn't easy to fathom, but it happens.
