but it's true.. I am telling you ppl, i know it for sure.. it is the spice, I think it called KARRY ( or something like that),which they use in thier food, and which has very strong smell. And then this smell comes out the pore with sweat.. it's not a sweat itself, it is this spice which comes out with sweat. And even the walls absorb this smell..that's why the houses where they use this spice for cooking, these houses have the same smell... So you can say it's not people who smells it's this spice that they use...
