Multilingualism protects against accelerated aging. I am not sure how I feel about this. “Learn a language” as the new “eat your broccoli”?

In a world obsessed with longevity, is brain health a reason to learn a language? I still hope the traditional reasons, like a love for other cultures, are the ones that matter most. But if brain health is an extra incentive or just makes language lovers feel even better, then why not?
