And humans are 1-3% microbes. Nothing stands alone in nature.
If by microbes you mean bacteria. Maybe we also contain fungus as well though.
And actually, if you're looking at cell count our cells are outnumbered by about 10:1, it's incredible!
Yes the human microbiome consists of fungus in addition to bacteria, protozoa and viruses.
On top of that, aren't there a bunch of studies or something that says our microbiome can affect emotions as well as what kinds of food we like to eat?
