Newman, I think the odor is more related to the region than anything. It might be more of a culture thing, for example if you and your family hadn't bathed for a year or 2, you may start to notice the smell but after a while you would think the smell is natural and probably wouldn't notice it. On the other hand, someone comes into your house and their probably thinking "stinky"
I think the same applys in that region, they probably think we smell funny too heh.
On the other hand, that does bring up a good point. I remember when I was on a highschool trip, we went into one of the dome places in the museum where they show the film on some ovalish screen. It was about dolphins or whatever and I had to sit next to this Indian or hindu lady. She had this smell like a dried salami that was sitting in the sun too long. I figured it was just her but i've noticed the same odor from many other Indians and Pakistanis. Many Arabs seem to have a similar smell for some reason. Not meant as an insult, but it is a bit awkward. I wouldn't say it's just the people in that region that have the smell however, Africans tend to have a distinct smell as well. Most Jews i've met don't appear to have an odor to me, unless we have some sort of odor that we can't smell or something? At the end of the day, anyone who doesn't use deodorant is probably going to smell bad.
