Dopamine Hi I m trying to work cooperatively but when you place an incorrect statement into the article and then add a cn tag after it it s hard to see how I can do anything except revert it Also let me point out that your edit borked the paragraph structure of the lead In most cases the first sentence of a paragraph should function as a topic sentence telling the reader the goal that the paragraph is intended to accomplish When you moved that sentence you gave the second paragraph a first sentence that is unrelated to the rest of its contents thereby violating the most basic principle of paragraph construction Regards
