Smallpox is too small and poxy.
GeneralI can only think of one predator that cities have, and that’s contagious disease. Which is great, because I don’t like cities, and people bother me quite a lot – especially in cities where they tow your car even when it’s parked right outside your house so they can dig up the road to fix a water leak WHICH YOU BLOODY REPORTED and then charge you £200 to get it back again – so roll on contagious disease! Yay!
