Behind the smell: our BO and Deo - Columns - livemint.com: "Sweat is the body’s natural cooling system, and on its own, is a non-controversial, quiet product of the eccrine and appocrine glands that has neither colour nor odour. But in some warm parts of the anatomy, like underarms, there nestle a whole host of bacteria, which feed on the organic matter of sweat and produce that thing called body odour (BO), the defining smell of local train and Metro travel in summer. That’s how sweat acquires a bad name."
