Which are the main reasons for learning a language Nowadays, lifestyles are governed by the globalized world where everyone lives in. Thus, some old traditions and customs, as well as languages are being affected by this phenomenon. Furthermore, this essential aspect of each culture, language, has to adapt to novel situations that 50 years ago were very unusual. For instance, international business and the need of speaking a foreign language. However, one can surmise that it would not be the only occasion where the knowledge of a second language could be useful. Likewise, it could be truly helpful if one is a freelancer and is working in their hometown, for instance, receiving tourist during the high season. By contrast, even if one has never had the opportunity of speaking a foreign language, several other reasons that justify the learning, could be mentioned. Firstly, to know another language besides the native one, is really useful for some kind of people, as researchers or scientists, because it dramatically increases the amount of information available on the Internet that one could understand. Secondly, it is useful for everybody in order to improve the health of the brain. That is to say, much one learns, better the brain will work. Moreover, it will improve its ability to memorize, focus and recover information. To conclude, be able to speak a foreign language is meaningful for the purpose of travelling or working abroad. Yet, it seems pertinent to remember that it is genuinely helpful for several other reasons, like having a healthy brain.
