Yes I think Bojo and co are also using a bit of psychology on us. Let it get to the point we are begging to lock down, because we can see what's happening. Shut us down for a month in that schools and non essentials close, plus vulnerable folk stay safe.
A gradual reopening in April til it starts climbing again, then we ask for lock downs again, get them possibly over May spring bank again using school holidays as a bit of a buffer for the economy.
Reopen june then we only have to get to mid july before it's the long summer holidays.
On the herd immunity I am praying it is something similar to chicken pox in that you get it then the majority of people have immunity. There will be some who get it a second time, possibly with additional complications but I think most viruses leave immunity behind as a parting gift.
Not everyone will get it and obviously there will be further outbreaks until we get a vaccine but with each outbreak there are fewer people to infect so the outbreaks are less intense each time.
That's what I am hoping is the case anyway. Because if it's not we might as well shove the old and the vulnerable behind a wall in Scotland or Devon or Yorkshire and the rest of the country just carry on as long as we can until a vaccine is found.
We are in a pretty bad place worldwide. We need to keep the wheels turning somehow. The rest of Europe can call on each other to help. Obviously we won't be able to do that and we do have to keep as stable economically as we can for what's to come.
People will die. It's inevitable. We can only try and minimise the deaths and unfortunately someone who is 80, maybe has dementia or some other life limitations isn't going to be a priority over a fit 40 year old. But we all know that. But what theu are trying to do is make what choices come obvious ones. So not drown the system so much that it's a choice between a relatively fit 60 year old and the 40 year old.
