No - using WD40 for arthritic joints ISN'T a wind up. I know someone who used a small amount of it on their knee, and weeks later, the pain still hasn't come back. Cod liver oil tabs were onced deemed alright, but it now transpires that the livers of cod contain toxins - which are then passed onto YOU. Glucosamine and additives can work, I believe, but often have a placebo effect. Unfortunately for people with arthritic knees or hips, replacements are often the only answer.
