Hi, A "Sanford and Son" marathon is on basic cable tonight, as I look at these episodes that I enjoyed as a child, Fred really shows signs of fibromyalgia. Sometimes he's in pain and too exhausted to do anything. Other times, he's very energetic. If he pushes himself too much, he crashes. Of course, the show attributed it to either laziness or aging. However, isn't that what people tell us? Just a thought.
