We really, really do.
I can currently hear a housemate sneezing outside my room door. One housemate keeps having her boyfriend to visit from Nottingham, wandering about the house sans mask. I'm expected to go to work on site with too many people for the space and facilities we have. Public transport is way too crowded to be able to keep your distance, given that there are so many dick-noses about.
I know that's all me, me, me, but there must be a great many risks, similar or different, that people are being subjected to, in this clown car crash.
No one can reasonably claim we don't have the benefit of hindsight, now. There are lots of roads to disaster, but the economic ones are all fixable, if there's the will to do it. Deaths and long-term debilitation aren't.
