The human body has 1.8T cells dedicated to defending it
It would be interesting to try to draw parallels with other complex systems.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?Is this already a formalized area of study?
