I believe that disease rates plummeted with the introduction of the automobile and generally faster means of transportation. You see, as people began to move faster, the various diseases couldn’t keep up with them. The diseases were too slow to infect people. Especially with airplanes and faster trains, disease rates dropped further.
This is the most terrifying and amusing thing I’ve read all day. The stupidity of this post is astounding. Like, people moving faster sheds the diseases inside them? Can a sprinter cure himself of the plague by running? It’s a good thing that germs can’t move fast enough to keep up with everyone in the enclosed cabin of an airplane.
