I could go and hug my mum, but it would put her and her household at risk
I actually agree with you, the risk is very very low, that's why I'm saying to people moaning that they can't see their mum or aunties and hug them to crack on!
I won't thanks, because in my mum's household are three vulnerable people and I would never ever forgive myself if I were the one to bring corona into the house. The risk is low, but still there, and whilst I know my own risk of dying is infinitesimal, theirs is not. So, having discussed it with them, we are all happy with the current state of affairs of continuing to shield that household, and my household being more open as I have two teens who go out with friends to parks/walks/take their dogs out.
Also, although my risk of dying is very very low, as a middle-aged single parent, I really don't want to get corona. I might be asymptomatic, or I could end up with a long-term chronic illness or damage to my lungs/heart. I don't fancy that as I am the sole earner in my family. So, I am more risk averse than perhaps others might be.
I think you have misunderstood my post- I'm suggesting that people assess their own risks, including their mental health, and act accordingly. Some people on here are acting as if they have no agency whatsoever, and actually, they could risk assess and do things differently, because I know several people who have done things on the boundaries/broken the rules/interpreted them liberally to keep themselves sane, and to me, that fine.
