#1 Feet Are The Smelliest Part Of The Human Body
The bacteria loves to rest in dark and damp places like sweaty shoes. Therefore, wearing shoes without socks will treat a feast to the little critters on your feet. These monsters then release acids that trigger the sharp smell.
One foot is said to have more than 250,000 sweat glands and they manage to produce a lot of sweat each day. Those with extra sweaty feet end up with a terrible musky smell.
In technical terms, they not only produce organic acids but stuff called volatile sulfur compounds that actually smells awful, almost like a rotten egg.
