Why we should learn a foreigner language?

 Language connects us to the others. Today, there are more than 6,500 spoken languages in the world. But, what benefits brings us the process of learning a new language? And I´m not talking about the bigger variety of jobs we can get, or the number of people we can meet around the globe. I´m referring to our brain, to see the advantages this can bring to our personal life.
 So, want to be smarter? Learn a language! Want to live longer? Learn a language! Want to learn how to learn? I don’t have to say it again ... Learn a Language! A lot of studies have been published talking about this topic, and the conclusions reveal: the process of learning a new tongue brings more advantages then disadvantages, and this can be done at any age. This is so a great thing that it also helps to delay the progression of Alzheimer´s disease.
