Is there such a thing as a good virus? I'm just theorizing about why both my wife and I have experienced a significant loss of appetite this week for no apparent reason. I'm just not hungry. My wife and I are both a little on the overweight side and we do terribly at dieting because our appetites typically tend to be so strong. So I'm thoroughly puzzled as to why both her appetite and mine suddenly went south this week. I couldn't care less about food. A small yogurt is about as much as I want to eat for a meal. It's weird. I'm not feeling any other adverse health effects, and neither is my wife. Could something in the water be doing it? Are there good viruses? I just can't imagine why this is happening. I'm not complaining, of course, but I am puzzled.
