Query: Guns, Zombies, and Steelhead Axes: cost-effective recommendations for
  surviving human societies   In pop culture, there are many strategies to curtail zombie apocalypses.
However, it remains unclear what routes we should take to eliminate zombies
effectively and affordably. So, we created a mathematical model to examine
interventions that armed adults with steelhead axes or provided enough
ammunition and a 9mm handgun to kill zombies in either a "single-tap" or
"double-tap". We investigate each case over two years under slow, moderate
speed, and fast zombies scenarios. We quantify health burden by zombies
averted, disability-adjusted life-years averted, and determine
cost-effectiveness using the incremental cost-effectiveness ratio. Our
predictions show the single=tap intervention is the best for stopping the
zombie apocalypse, as it would avert hundreds of millions of zombies and deaths
while also being the most cost-effective intervention. Altogether, this
suggests conserving ammunition and supplying ranged weapons would be an
effective use of limited resources in the event of a zombie uprising.
