Well, I have 2 degrees, several TAFE certs and 6 languages under my belt. Don't regret any of them.
My last degree - B. Sc (Microbiology major, Medical Microbiology minor) was finished only 5 years ago. Never once used it directly, but it sure opened other job doors where they needed a degree. I'm 48
Maybe try learning a language Hans - like I said, I am up to 6 - feel confidently fluent in English (maybe
), Russian, French and conversant in Swiss-German, Norwegian and very basic Suomi (just ask Matt
). It truly does keep your brain active, because you truly don't know a language until you dream in that language. I've dreamt in French and Russian for years now.
