I've actually spent about half of my life overseas in the third world. I grew up in Tanzania, East Africa, and later lived in South-West Asia. In general, everywhere I go, I am treated with great respect and hospitality, but I need to be sensitive to cultural, tribal and ethical customs of the local people. In this modern era of technology, I think we forget that the most important thing when traveling is to listen and learn, and establish relationship, and not be hidden behind technology like Goretex, emails, satellite phones, and insulated from the people around you.
