Correct. It is like things like Latin being taught. No doubt a classic subject, but what
practical use is it? Not going to help you with negotiating with a pack of Indians who

Well, I know 'curriculum vitae', 'ad hominem' and a few other random phrases, but in the main, useless unless you're a biologist or a doctor.
