So in order to 'get a handle' on the CV19 crisis - in as empirical way as I can muster; so that I can make rational life choices NOW - not in a year or so's time when all the data has come in - when it'll be too late, basically, I follow the reported trend of 80% of CV19 case deaths over 65 years, and ~70% all case deaths having comorbidities.
This means that if a person under 65 years catches CV19, and the mortality rate is 2% of all cases (moderate figure), then mortality rate for under 65 years is 20% of 2% = 0.4%, and for anyone under 65 years lacking comorbidity, then it's 30% of that 0.4% = 0.12%.
Since I am under 65 years and lack a comorbidity, then I assume that my chances of dying from CV19 are, at most, 1 in a 1000 - pretty slim.
I assume that is why so many under-65s are happy to go out in the sunshine - on Weston promenade, for example, without masks and in close proximity to other people.
Because firstly they have to catch it, and then they have at most 1/1000 chance of dying, which was, for example, apparently the death rate of expectant new mothers in US/UK in 1950s.
As regards 'save the elderly,' well, perhaps there are clear divides between the 'boomer' generations and the younger groups of today, for example Brexit/Conservative voting:


Perhaps many young people could be thinking they're doing themselves and their country 'a favour' by spreading CV19 around....
