I have reverted two of your edits to History of medicine which, without offered reasonable explanation, discussion or supporting references, appear to be mere opinion. Note that at least two other edits of yours similarly have been reverted by other editors. Your current opinion on a matter is not by itself sufficient justification for edits.
