Handwashing for the Apple Watch happily slotted alongside face masks for Memojis in the list of COVID-19-related features the company introduced at last week’s WWDC keynote. It’s a pedestrian action, something we take entirely for granted the several times a day we do it. Over the past five months, however, handwashing has taken on a kind of central importance to our daily lives — something to focus on and obsess over.

We all read the WHO and CDC guidelines and shared (and perhaps even created) some of the millions of song lyric memes highlighting the proper length of time required to sufficiently clean one’s hands and avoid virus transmission. We’ve all also become painfully aware of just how long 20 seconds can feel when you’re standing in front of the bathroom sink.
