A mere six months ago, nobody would have imagined a world that is in the grips of a global COVID-19 pandemic, let alone one that would wreak havoc across health systems and the global economy. I still vividly remember at the beginning of the year reading about the first lockdowns overseas and thinking how remarkable it was to ask humans to stay in one place for such a long period of time; it just seemed unfathomable. And yet here we are, having shut our borders and moved into lockdown and collectively built a wall of defence to a virus that was closing in on the world. There are few things now that I think I will ever consider to be outside the bounds of possibility any more.
