I personally respect and truly admire people, whose professions are:
doctors (they can really know all the clever words, make diagnosis and cure people). Special category here is sugreons (those who SHOULD cut)
social service workers (those who work with persons with disability)
pilots (these guys I can admire: they can fly with people and feel no fear/or they don't show their fear)
teachers ('specially in special schools)
policemen (they risk their life everyday for people who they do not know)
firefighters (the same thing as cops)
attorneys (they are rather greed, but that doesn't mean that they are useless)
