After Cannae, Rome couldn't defeat Hannibal in open battle, so they adopted a strategy of avoidance, creating a stalemate. For a power on the brink of collapse, simply surviving is a form of victory. This prolonged timeline allowed Rome to regroup, rebuild its manpower, and ultimately go on the offensive.

Targeting a regime's leader, assuming it will cause collapse, is a fallacy. Resilient, adaptive regimes often replace the fallen leader with a more aggressive individual who is incentivized to lash back simply to establish their own credibility and power.

Unlike typical pathogens, mirror bacteria would be immune to their natural predators like viruses (bacteriophages). This advantage could allow them to proliferate uncontrollably in soil and oceans, creating a permanent environmental reservoir for infection and potentially outcompeting essential natural microbes.

When a vaccine successfully eliminates dominant bacterial strains (serotypes), it creates a niche for non-covered strains to emerge and cause disease. This phenomenon, "serotype replacement," means narrowly focused vaccines can become victims of their own success by shifting the landscape of infectious threats.

Evolutionary modeling shows that taking antibiotics beyond symptom resolution can be counterproductive. It needlessly kills off susceptible bacteria, creating a perfect environment for resistant strains to flourish. The optimal strategy is often to stop once the immune system can handle the rest, contrary to decades of medical advice.

Our primal fear responses can lead to well-intentioned but counterproductive actions. For instance, fearing germs leads to over-cleanliness that may increase allergies, and fearing for bee populations leads people to build backyard hives that harm vulnerable native bee species.

A tumor can be viewed as an evolving system within the body's environment. It progresses from stage to stage by "ratcheting up" its functional information—its ability to survive and grow. This evolutionary framework could inspire novel cancer treatments.

To win the evolutionary game, one can either increase their own reproductive success (the gas pedal) or actively inhibit the reproductive success of rivals (the brake pedal). Both strategies increase an individual's net reproductive success relative to the population.

A common misconception is that engineered life would be feeble like current lab-created 'minimal cells'. In reality, a bad actor would create a mirror version of a naturally robust bacterium like E. coli, not a fragile lab specimen, to ensure its survival and virulence in the natural environment.
