My question was a poor attempt at trying to be ironic, given that those 'in power' like to set mythical milestones which really have no meaning in real life, as you have clearly illustrated.
As retired member of the NHS, I know that risk will continue and will rise & fall over time, much as it did during the mid-20th Century for conditions such as TB, Diphtheria etc. It is up to the individual to decide what level of risk they are willing to take. This no doubt will be informed over time as it becomes clearer which of the underlying conditions in the groups already identified by the NHS are likely to cause the greatest risk of death.
This is illustrated by the recent death of my father, not from Covid-19, but because he was unwilling to risk going to hospital for another serious condition. Unlike some in power I judged the risk of travelling a long distant to attend his funeral last week was still too great, although I suspect I will soon venture out to walk the dog in the village where we live, suitably protected.
