I can see it would be quite easy to feel like that. To my surprise I'm quite enjoying lockdown and not having to do things all the time. And wondering if I'm getting rather comfortable and almost institutionalised.
But I'm making myself go out for some good exercise, for mental health as much as physical, and because, I live in a busy place, I pass a lot of people. I find it encouraging that, as a PP said, people are out and about going about their business. They look well and happy and I think that the chances of any of them being a threat to me are very small. There are quite a lot of narrow points round here and I've passed within a couple of feet of people occasionally and I'm none the worse for it.
I've also seen a few friends, from a distance or online, who have been very ill with Covid and recovered. They look good now. And there's Boris, of course.
So I have plenty of evidence that most people are either not getting Covid, are not very ill with it, or recover eventually. Anything could happen, but the odds are in my favour, so I mustn't let fear do damage that the virus probably won't.
