## Why It's Good For The Game

I PR'd the original with the intent of making disease battling more
engaging by adding warnings and sneeze dodging, but this was rejected
and instead we got a very awkward middle ground where no one is happy
and the original PR didnt accomplish what it set out to accomplish. You
can't dodge the sneeze because it's a shotgun spread and invisible :/.
The sneeze catchers are even somewhat buggy and the sneeze warning leads
to extra chat clutter
