So... What do I Pack?

Ok...I'm staring at an empty suitcase. How do you pack for a third world country? Ben, from GFR, sent us the list: Purell, Plane ticket, sleeping bag, pillow, towel tolietries, snacks, peanut butter, jelly, water bottle, cereal, camera, journal & the Bible. Of course there are luxury items to consider...like your laptop, a change of clothes for everyday, a razor. Do I really need to bring a razor? Will the Ugandans really care if I have hairy legs or armpits...doubtful, but it's one of those luxury items that normally we would feel to be a necessity for any other trip. The point is, I'm trying not think like a spoiled American when I'm packing...I will be surrounded by people that have nothing and I don't want to look like a tourist. As one of my old friends said to me this weekend, "how does a 5'2'' blonde blend in?" I guess I can't.
