I&#x27;m familiar with ruminants and the concept wrt digestion - I think what throws me most about the Wikipedia page on the psych concept is what it means to &quot;focus on the symptoms of one&#x27;s distress&quot;. I thought distress was a symptom itself of other conditions. A symptom of distress would probably be inability to focus but then how could you possibly focus on that!<p>&gt;a thought process where one is going through the same steps over and over and over again; you can pick apart any situation you find yourself in, in excruciating detail &#x2F;&#x2F;<p>That&#x27;s a very clear description, thank you. If that&#x27;s all they mean then IMO the page is absolutely terribly written.
