I don't think CV is a hoax (I wish it was!!!!), but I'll tell you why it took me a long time to take it seriously, and I still barely do; I'm obeying the lockdown exceedingly grudgingly, especially as the government is playing mind games.
Because the press have a history of always telling us that we're going to die from something or other, or there will be total Armageddon because somebody sneezed. We had it with the Millennium Bug, that you would die from using your mobile phone, foot and mouth, mad cow disease, cancer from your pen top, immigration, terrorists/paedophiles/extremists round every corner, to name but a few.
So when there was all the talk of the "deadly virus", all the crying wolf that the press had done over the years made me, and no doubt many others think "yet more press hysteria".
I now live by the principle that in general, news is bad for you, and that what's often more telling is what you're not told; right now, I think the government's silence on many things speaks volumes. I remember an article which listed many reasons for the news being bad for you, one of them being "it appears impartial, but there's an agenda behind it". I especially believe this of anything the government says, that what they say is to distract us from what they don't want us to think about. They're throwing death figures at us all the time because they don't want us to be plotting ways to break the lockdown.
