Learning another language may be one of the best ways to keep your brain healthy

    All of the the research I have seen on this topic have been observational retrospective studies, which are worthless and should be ignored. The confounders on the group of people who are able to learn a second language (let alone a third or more) are so large that they cannot be overcome without a randomized control. This stuff is churnalism, right up there with "does coffee make you live longer?" [1].

    But, as someone who has now devoted a large portion of my life to becoming proficient at a second language, I do think there are benefits, even if they've never been proven. The most important of these, in my opinion, is just the social aspects of learning another language. You have to get out there and talk to people, and that's inherently healthy.

    I do want to say that you hear loads of pessimism about whether or not it's possible a language after childhood, etc., but I'm here to tell you that not only is it possible, it's possible to do even if you suck at languages (as I do). The primary factor is motivation, and the second biggest factor is time. Find a language that you like, because you like the culture you'll be interacting with when you speak it. If you don't, you'll never find the impetus to keep going when it gets hard and boring.

    [1] protip: drink coffee if you like it, and don't worry about it. Likewise, learn a language if you like it, not because some dumb article said it would make your neurons fluffier.

      I am an actual linguist, in a subfield that requires me to continually learn new languages, and there are no social benefits. I definitely don't get out there. Once one is a man over the age of 40 or so, local people are rarely willing to talk to you at any length, you are not interesting any more (in fact, in some cultures, local people will have heightened suspicion of you). Language learning becomes more a passive endeavour with few opportunities for real-world speaking.

        This is either a problem with you, or a problem with the specific place you live in.

        I talk to people every day in my 2nd language. They are generally delighted to do so.

        Yes, some people are suspicious of me, depending on the context. But even then I can generally disarm it with body language etc, because I'm a skilled and empathetic human.

          Your post history suggests your sole personal experience is Spanish. Congratulations, you lucked out learning the language of speakers more likely to be friendly and sociable than not (though there are corners of Latin America colder than others). But that experience will not be representative of many other languages spoken by other peoples.

            You made a blanket statement about being a man over 40 makes it impossible to converse with people. I refuted that. Would you like to revise it to say "I happen to be in a place(s) where people are just generally anti-social, so that makes it difficult to practice a language"?

              Since my late teens, I have spent ~6 months a year traveling the world, and language learning has been a big part of that. And now I am in my 40s having seen how, in most regions, interest from locals in intensive conversation steadily diminished as I approached middle age. So, my experience has been comprehensive enough to make such a blanket statement.

                When you are "home", do you have the same problem? I wonder if people are becoming less social overall?

                I also wonder if it is something that happens for women as well, or just men.
