This news caught my attention last night. It was about people who are still untouhed by our modern civilisation. Here are some pictures I found on BBC news' website:


According to the news I saw last night, these tribesmen were running frantically when a helicopter first flew past that area. But when the pilot returned, some of the tribesmen started to shoot arrows at him, as shown in the picture above. This clearly showed that they have not been in touch with the outside. (everyone knows that your average bow and arrow cannot penetrate a helicopter) I guess they must have thought that the helicopter were monsters.
