by the numbers
(from my national geographic 'the science book' I'm reading)
Human bodies consist of about 10 trillion cells. (by continuous cell division from the original single ONE cell!) that's 10 to the 13th.
The gastrointestinal tract contains about 100 trillion cells of microorganisms
and
there are Another trillion bacterial organisms on your skin.
(but these all weigh only 3.5 oz due to the size difference)
It takes a village!
