The human body has 1.8T cells dedicated to defending it
It would be interesting to try to draw parallels with other complex systems.<p>e.g. Is the percentage of mass or resource allocation to a body's immune system similar to that devoted to a nation state's military and police force? Do all complex systems naturally normalize on a similar percentage devoted to defense that maximizes resources going to non defense productivity without leaving the system too vulnerable to attack?<p>Is this already a formalized area of study?
