When Size Doesn't Matter


Did you know that humans are outnumbered ten to one by the bacteria living on our skin and inside our body? According to this ratio, that means our body can only be classified as ten percent human.

In fact, these 100 trillion individual microbes can be regarded as a virtual organ with a larger output than the liver.

But before you run off to the decontamination shower, remember that each of those microbes performs a very important function. Without them, we would die due to lack of an immune system, and an inability to digest food and absorb nutrients, or to produce vitamins. The human gut alone contains almost two kilos of bacteria.

Microbes also protect us against pathogens (the badasses of the bacteria world), so it’s okay to love your microbes.
