I heard this yesterday from someone DH works with (they're all wfh). A couple in their late 40s, no health issues with no vulnerabilities, fully vaccinated but 'you can't be too careful'.
They've not left the house apart from their vaccine appointments since the start of the first lockdown.
I understand how worrying it's all been for some people, particularly if you're vulnerable or have health anxiety. But it's so sad that people are this terrified. I wonder how they'll cope when restrictions end. The MH fallout from all this is going to be massive, isn't it?
