A new born human comprises very few micro-biologies while an adult human can comprise tens of trillions micro-biologies that represent a considerable (30% or more) percentage of the total mass/volume of a human body.
How the individual micro-biologies interact with each other and the human body and drive conciousness is currently an area of intense study.
Even when a single tear rolls from your eyes down your face and into your mouth or ear, a phenomenal chain of micro-biological responses take place, which the dullards that we are usually just ignores until something disturbing takes place.
Is it an itch that we scratch through some response of our neural network, or is it a community of micro-biologies telling us that something is not quite right and needs our attention.
Recent studies have shown that micro-biologies of the gut exercise considerable influence over the human brain, not just for alleviating hunger or thirst, but impart the will to live and do a wide range of things.
There are some fascinating videos online concerning slime. One shows a gathering of slime building themsleves up into a tower for priviledged few of their number to mate and reproduce. Another shows a slime negotiating a maze and yet another controlling a machine. Not matter how thoroughly and often we may wash ourselves, there are always little communities of slime in and upon us.
