Having seen the most recent photos of Jacinda Ardern and Dr Bloomfield the strain of this is starting to show on their faces. I shudder to think of the stress levels these folk and others working very hard for Kiwis are under. It is sometimes easy to forget that.
Late nights, early mornings. When you are hard at it brain use wise, you cant just go to sleep. And its tiring. It takes time to calm down. Add in worry.
