If you have Micrococcus sedentarius on your feet and in your sneakers, will anyone notice?

Oh, yeah. You will have very stinky feet. We don't mean regular nasty gym shoe smell. We mean almost knock you over kind of stink. Micrococcus sedentarius (say: my-kroh-kah-kus seh-den-tair-ee-us) is a kind of bacteria that grows on extra-sweaty feet. It contains volatile sulfur compounds - the same stuff that's in rotten eggs.
