My mother has that. Coupled with her fibromalgia and carpal tunnel, she is in CONSTANT pain and stays depressed a lot. But she is not lazy at all! And she wasn't as a child either. She was, however, in a pretty bad car accident as a child and has had numerous factory jobs and is one of those people that scurry around the house cleaning and tidying up every day (though, she's a bit slower at that now). It makes me very sad to see her in pain, and the medicine never works.
