What career does German help with?
I was thinking of encouraging him to take Latin - it would help with anything medical or with the derivation of English words. I took Russian, since I majored in metallurgical engineering and at that time, the Soviets were leaders in the field.
Engineering for one. I am an industrial electrician in the printing industry and about 50% of the machines come from Germany. It may not be all that helpful in today's world. Studying German was beneficial to me. It's close to english and it helped me see the roots of the english language. Latin is a pretty good choice, too.
