Consider the different types of sweat glands. Those in the armpits and pubic area have cells that break down completely and the debris becomes a source of food for bacteria whose action produces the smells of body odour.
Other sweat glands secrete a solution of water and salt, so they don't create the same smell. These facts can be used to emphasise the importance of good hygiene.
