When the microscope was first invented, papers in England published drawings of what was seen under the microscope in a droplet of water taken from a freshly-brewed cup of tea (Earl Gray, hot... I assume). The image showed a whole slew of benign micro-organisms.

There was a mass panic.

People who had been drinking tea and, presumably, ingesting exactly those organisms their entire lives lost their minds. There was even talk of government action at the time. To what possible effect? I have no idea. But there was talk. There's a great deal of work done in sanitation which has lifted humanity up, it's true. But it breeds a kind of hypochondria that is as pathetic as it is useless.

This is all to say: Fuck Karen. And not in the fun way.
