While researching whether it will be important to wear camouflage with zombie forces out and about, I ran across this site. Lots of useful information.
Sight: due to degradation of their corneas, zombies suffer from severe myopia. In addition, they are colorblind.
Hearing: zombies go deaf within a few weeks of transformation. Efforts to rehabilitate them through ASL training have thus far proved unsuccessful.
Smell: zombies have even more receptor cells than vampires. If the wind is right, zombies can smell humans from as far as several miles away.
So, disguising our scent is more important it seems. I’ll be looking into what that means later.
