Those who speak more than one language have the ability to process information in a more logical fashion. For instance, rather than making decisions based on emotion, those who had to consider decisions in a foreign language made wiser decisions based on analytical reasoning. This may also explain why bilingual students tend to score better than their peers on academic tests. Whether you are traveling abroad or doing business with someone abroad over the phone, the ability to communicate is essential. When you learn to speak another language, communication becomes easier. As you travel, you will be able to find out information yourself rather than rely on translators.
