Learning a new language can be useful but also it can represent a real challenge. There are so many factors to keep in mind when you do so. Children can absorb information very rapidly and until they are 6 years old they can learn very easily a new language or even more languages, depending how exposed they are to it as well. As time goes by it can be harder to take up a new language, so for adults and elderly people it can get very hard. Still, there is hope… depending on the methods that you use.
