One can listen to that list and assume that several things may be the cause. If a person stops eating, maybe that's a cause of disease or there's illness. It's a little bit like detective work. That's why I say it's a relationship of trust. Oftentimes I find, especially for professionals, that if their instincts are up, they should be aware of those instincts, because people have a lot of experience, and if it doesn't fit the norm it usually is not the norm.
