You choose such an edge case question - how about this sort of thing: Which is the best political party? Are the side effects to X medical treatment? I bet there are even cases when eating rocks is ok! PS It has been written about: https://www.atharjaber.com/works/writings/the-art-of-eating-rocks/ https://www.atharjaber.com/works/writings/the-art-of-eating-... > Lithophagia is a subset of geophagia and is a habit of eating pebbles or rocks. In the setting of famine and poverty, consuming earth matter may serve as an appetite suppressant or filler. Geophagia has also been recorded in patients with anorexia nervosa. However, this behavior is usually associated with pregnancy and iron deficiency. It is also linked to mental health conditions, including obsessive-compulsive disorder. Would you deny a starving person information on an appetite suppressant?
