For some people, usually refugees, travelling is not so much important as essential. For others, taking a year out to travel the world will help them to gain a much better understanding of the different cultures that exist in foreign parts. It is common for western young adults to take a so-called gap year before they embark on higher education to travel the world. This has historical roots in the grand tours that many noblemen – and some women – would take part in during the 18th and 19th centuries. Such travelling and the documentation of it helps people all over the globe to understand one another more.
