The Kid Should See This

What’s the dirtiest place in your home?

Think of the dust, the hidden ants and spiders, or the potential molds, fungi, and bacteria that can be in any household. Is the dirtiest place in your home under your bed? On doorknobs? In the dishwashing sponge? In the toilet? This Science Insider video reveals that the ‘dirtiest’ place in our homes are on our bodies. There are microbes in our armpits and in our guts, mites on our faces, and “some 100 species of fungus living on our feet“…

And while the idea of them might give you chills…microbes like these help keep you safe. You see, the number of harmless microbial species in the world outnumber harmful ones by a trillion to one. In fact, less than .00000001% of microbial species account for nearly all infectious diseases in the world. And all these harmless bacteria crawling on your skin means less room and resources for pathogens, like antibiotic-resistant microbes.
