know two languages make it more intelligent. Learning a new language changes our brain, if you have 4 years or if you have 84. These changes are permanents and concern structure and function of our brain. Researchers from Pennsylvania University observed the brain activity with 39 volunteers learning Chinese. After two magnetic resonance scans (the first at the beginning, the second after 6 weeks) they demonstrate that compared to the group that didn't participate in the lessons, the others had a strengthen cerebral connections, flexibility of brain, efficiency and good performance. The changes was independently of the ages . Although before scientists say that over 6-7 years we can't learning like a native speaker, today psycholinguistics are not agree. If children learn faster is because they haven't an "ego" and a reputation to protect, and they don't have afraid to say nonsense and get it attempts. We can just talk of declination but we can get an excellent level also when we are 70! Finally, learning 2-3 languages retard for 4 years the appearance of Alzheimer and dementia. But learning languages is more than that because in the Edinburgh University researchers say that know two languages make it more intelligent. For me, I love languages but not for brain, for the possibility to changes our-self, our opinions, knowing new people, new cultures, and because thanks to this we develop empathy, sensibility, curiosity, and a deep comprehension about different people. But especially because we learn to love everything and everyone.
