Learning a second language
Learning more than one language is easy - if you do it before you are seven years old. Up to that age, the language areas of your brain can change, depending on the speech you hear. Later, these areas are 'wired-up', and learning another language is much harder. If you learn two languages early in life, the same area of your brain deals with both. Some researchers believe that if you learn a second language later in life, you use a different area of your brain.
