For me I had two years of French in high school and another two years in Junior College. So I had a passing knowledge of French. Sometimes I break out in a phrase or two because I like it. I also know some Spanish from what I learned in grammar school. Not enough to really converse at any length with anyone but enough sometimes to understand what's being said even if I can't reply in like kind.
Should those interested in Science learn GERMAN? Are you interested in any languages and if so are you fluent in more than one?
