EmpiricalRequires evidence

The dominant disease class runs on four modifiable behaviours, which means the bottleneck is not biological. Part I cites a WHO report finding that the highest burden of non-communicable disease is imposed by conditions sharing the same four major risk factors: tobacco use, harmful use of alcohol, unhealthy diets and physical inactivity. Every one is a behaviour rather than a pathogen or a genetic endowment. That is why Part I treats the problem as a disconnect between modern lifestyles and evolutionary programming, and it is also why the problem is tractable in principle and intractable in practice: the four factors are each produced by industries that profit from them.
