Odor judges perform odor tests to rate the effectiveness of hygiene products like soaps and bodywashes, deodorant, and mouthwashes. Depending on what products are being studied, judges smell subjects' armpits, feet, or breath and rate their odors on a scale of one to 10.
During one odor tester's 15-year career she sniffed approximately 5,600 feet and an indeterminate number of armpits, for which she won the Guiness World Record for most feet and armpits sniffed.
