If there was ever a time to hug a scientist, now is that time. But please don’t. Instead, try your favorite “Coronavirus Hello,” which I think is no longer supposed to be a elbow-bump (too close to the sneeze-catching crook of the arm). So, maybe try some jazz hands, instead. Hellooooo, you might say from a safe social distance, waggling your fingers winningly, to show gratitude for the humans who are working hard to save our lives, right this very moment.
