Gah - that is a bad conclusion to draw from that study.  There are some 39 trillion bacterial cells in a human body, and ~30 trillion &#x27;human&#x27; cells in our body. EXCEPT that 25 of the 30 trillion human cells in our body don&#x27;t even have any human DNA in them (red blood cells lack a nucleus, cannot divide, and do not contain human genetic information).<p>It&#x27;s hard to count human cells, and non-human cells.  Counting mass, nuclei, activity, etc. are all different.<p>The original hypothesis still stands - a truly significant portion of you is not human.
