I couldn't think of anything more useless to waste my time on. While you're at it, you might as well learn Ancient Greek and Aramaic.
Seriously, though, you won't need it enough in aviation to make the time spent a worthwhile investment, if that's your sole reason for doing it. Learn French if you fancy learning a new language. At least with French you can order good food (I was going to say you could pick up chicks, but then I noticed you're married, so, no factor there)
