Where does masticating guns fall under the rules of safety? And why so narrowly focused on helping your colon recover from cancer surgery? Does this mean it is not helpful for after having a colonostomy or a prostate exam? Does it matter what type of gun? What about the parts: is the barrel more effective than the butt stock? How does this differ from those who just chew on trees or scrap iron? There are a lot of questions that this headline brings up.
Most important though, we need to find out where this kind of research was funded.
