Okay, you’ve had a tough day at the office. But at least you’re not working as a “barnyard masturbator”. Or a “corpse-flower grower”. Or a “flatus odor judge.”

Those are a few of what Popular Science has determined are “The Worst Jobs In Science.” Their list is online here, so you can check it out — in all its gut-wrenching glory — for yourself. Oh, and that “flatus odor judge”? In case you’re looking to change careers, the job description is thus:

Odor judges are common in the research labs of mouthwash companies, where the halitosis-inflicted blow great gusts of breath in their faces to test product efficacy. But Minneapolis gastroenterologist Michael Levitt recently took the job to another level—or, rather, to the other end. Levitt paid two brave souls to indulge repeatedly in the odors of other people’s farts. (Levitt refuses to divulge the remuneration, but it would seem safe to characterize it thusly: Not enough.) Sixteen healthy subjects volunteered to eat pinto beans and insert small plastic collection tubes into their anuses (worst-job runners-up, to be sure). After each “episode of flatulence,” Levitt syringed the gas into a discrete container, rigorously maintaining fart integrity. The odor judges then sat down with at least 100 samples, opened the caps one at a time, and inhaled robustly. As their faces writhed in agony, they rated just how noxious the smell was. The samples were also chemically analyzed, and—eureka!—Levitt determined definitively the most malodorous component of the human flatus: hydrogen sulfide.

I’m going to throw up right now.
