On Friday, the Centers for Disease Control recommended that every American wear a face covering when in public. Masks will be the hot, bold look for summer.

The medical evidence for the practice is overwhelming. The post-SARS countries in East Asia have known this for a long time, and America and Europe are finally coming around. I’ve put a bunch of resources about the medical benefits of mask wearing in a further reading section at the bottom of this post.

But in this essay, I want to persuade you not just to wear a mask, but to go beyond the new CDC guidelines and help make mask wearing a social norm. That means always wearing a mask when you go out in public, and becoming a pest and nuisance to the people in your life until they do the same.

A very persuasive essay from Maciej Cegłowski, the founder of Pinboard, about the whys and hows of wearing masks in public. I started wearing one yesterday for the limited time I was outside, and the medical community seems to now be recommending that everyone do the same. It’s also worth reading Ben Thompson’s take and checking out these simple mask-making instructions from Loren Brichter.
