I said it upthread but will say it again.
For most people this is a seasonal flu type thing. You will probably be ill from it. You probably won't die IF you get the right medical treatment. The NHS cant treat everyone at the same time so it's to slow not stop transmission anyway.
We can't stop the world for a year. Or even the UK. So it's either gamble on herd immunity or it is literally survival of the fittest for 12 to 18 months. We would starve to death before then.
People screaming to close schools, wfh, go into lock down haven't given a thought to the poor buggers making sure that there is still food, still medical staff, still electric when you switch the switch.
Telling the most vulnerable in society to stat home is an obvious solution. If you personally want to isolate yourself crack on. You don't need Bojo to tell you that you can. The impact on you and your family won't be pleasant in some cases (no work, no money blah blah blah) but a country wide lock down just means many more people suffer the same thing.
There is no cure . No vaccine. No magic wand. Keeping the most vulnerable as safe as we can while the less vulnerable go about the business of keeping lights on, food in the shops and doctors to treat us all is the most logical and sensible thing.
And I am a lifelong labour supporter and bloody hated Bojo before all this. The man has balls of steel and is actually protecting all of us in spite of what the rest of Europe and the world is doing.
The vulnerable need our help and support right now and that's the best thing we can do.
