In their country water is more scarce than it is here. We are pretty much the only country in the world (and maybe Canada) that take showers every single day.
Most all other countries laugh at us for being so wasteful (which is pretty valid if you look at it).
Not to mention that the traditional Indian diet is high in spices to trigger the cooling effect that the endorphins released when spicy food is ingested.
As a side effect, when these spices are metabolised, they (and their byproducts) tend to get into the sweat and various other bodily excretions and they are odiferous in nature - curry most strongly comes to mind.
Generally speaking though, you sound like a total dipshit the way you worded it.
