Travel they say is just either for business or for pleasure. But they didn’t know that some people would travel for emergency purposes or health purposes. Some people who has some problem with their health would risk to go different places just to get the right treatment for them. Just like in Africa which has a very few source of medical treatment, they would fly to US to get medicine or people would travel in Africa to provide medicine and treatment. I even remember a friend of mine one flew to Europe to get the new melody open fit hearing aids for her grandmother so she can hear better since this was the type of hearing aid that was recommended by their doctor.
