Summary:

- Speaking multiple languages can help keep the brain younger and healthier as people age. Researchers found that bilingual individuals tend to have better cognitive abilities and brain function compared to those who only speak one language.

- The study suggests that learning and using multiple languages exercises the brain, which can help protect it from age-related decline. This cognitive benefit seems to last even after people stop using their second language regularly.

- Multilingualism may help delay the onset of dementia and other age-related brain disorders. The mental exercise involved in switching between languages on a regular basis appears to strengthen the brain's resilience and adaptability over time.
