Yes there is. The death rate for anyone under 60 without a major health condition are tiny. Extraordinarily so. Only a few hundred people in the UK in that category have died from of a population of circa 65m. There is BS modelling that govts rely on (and try to scare people with) then there is the actual EVIDENCE.I look at the British Prime Minister and I look at the average Joe walking around Melbourne and health wise I don’t see any difference between him and 50% of the average Joes. And COViD put him into ICU. There’s nothing abstract about the idea that the situation he found himself in, could apply to large swathes of the general population. And whilst the restrictions are onerous, I’d prefer that to suffering Boris’s fate. And I’m sure I’m not alone on that front.
If you are worried then lock yourself away. Its a bit rich however to tell others they should do the same.
