His work1 analyzed the volatile organic compounds (VOCs) emitted from human skin; however, instead of sampling VOCs from the axillae (underarms) considered the primary source of human body odor, his team sampled from non-axillary skin, including the upper back and forearms, that also emits volatile metabolites.
