Opinion | Coronavirus crisis: why wearing masks in panicking Hong Kong makes us more miserable
- Studies have shown we recognise happy emotions from scanning the lower half of other faces and negative feelings from the top half. In a city where everyone is wearing a mask, the emotions that register these days are panic and anger

I’ve worn a mask every day for the past month. The first few days I’d forget it in the morning. I’d stand in the lift and look at myself in the mirror before suddenly realising, “Shoot! My mask,” and then I’d make my way back upstairs, awkwardly smiling at the guard as I pass by him again.
But, by now, it has become routine – phone, keys, wallet, mask. I tie little loops into the strings to keep the mask tighter around my face. I pinch the wire around my nose and pull the fabric down over my chin. Ten hours a day I’m anonymous. Expressionless. Shielded in baby blue.
I look around me, at the various shades of surgical blue and wonder what it does to a human to not see faces, except for a select few, for weeks at a time. Studies have shown that we recognise happy emotions from scanning the lower half of other faces, and negative emotions from the top half.
