Thank you. But my inadequate brain tells me we will all get exposed to this at some point until herd immunity is achieved. This is not going away for a couple of years lockdown or not.
If you really don't get it why not volunteer in your local hospital as a porter or cleaner? That way you might learn a thing or two and help achieve your own immunity as part of the herd ... or not.
I gladly would if I was not a key worker already. I am aged well over 60 and have recovered from life threatening cancers twice 3 and 17 years ago (and so am probably in a high risk group) but am working normally and so I am practising what I preach, as I am more at risk than those sitting at home. My view is that if your number is up then so be it.
Frankly, if you've got that sort of "don't care, it's all a fuss about nothing" attitude, I hope your key working takes you nowhere near anybody else - whether colleagues or members of the public.
It's all very well, you being a danger to yourself - being a danger to everybody else is a different matter altogether.
