Not sure if I should believe everything on the internet. Yahoo especially is notorious to posting these nonsense, exaggerated stories. Smelling fart could prevent disease and even cancer?
The next time someone at your office lets out a "silent but deadly" emission, maybe you should thank them. A new study at the University of Exeter suggests that exposure to hydrogen sulfide — a.k.a. what your body produces as bacteria breaks down food, causing gas — could prevent mitochondria damage. Yep, the implication is what you're thinking: People are taking the research to mean that smelling farts could prevent disease and even cancer.
