But it doesn't disprove anything either. The expert who is claiming you need to spend money to solve an issue the expert says is a dire issue, doesn't know the basic math regarding the very subject she is talking about . You ok with your mechanic not knowing how an engine works but wants to charge you a lot of money to "fix" your working car? Or about a doctor who is diagnosing you with diabetes when they do not know what a good fasting reading is or what insulin even is? Are you ok with that? It doesn't mean she is wrong, it doesn't mean she is right, it means she doesn't know enough to comment on the matter.
