I have a problem with the classification of traits as mental disorders, which may be a huge boon in the right situation. A friend of mine could be classified as compulsive/obsessive. He works as an airplane mechanic. I would rather ride a plane that he worked on, than his "normal" colleague, who talked to someone else while refilling a tank with pure oxygen, walking away and having his arm catch fire from a static discharge. No snark intended.
