Another attempt at a patient explanation: Personally, I wouldn't really call the current level of work, family and social life "lockdown" anymore. Big parts of life have returned to a significant degree of "normal", even more so if school reopening can be managed.
If we were to take everyone over 70 out of circulation, plus the estimated 15-30% (I think) of younger people with known pre-existing conditions, life would be anything but normal.
Many teachers wouldn't be able to teach, volunteers unable to volunteer, grandparents unable to look after their grandchildren etc.
Never mind the fact that these many millions of people might have some thoughts about this, too!
If I am looking around me, I see many people looking pretty happy having a coffee with their elderly mum, or grandparents taking kids out for a treat. Seems to me that most people value and appreciate this level of togetherness over being able to go into a football stadium or to a massive concert or whatever it is that would need to happen to call it normal?
Another thing is that currently there is quite a bit more scope for people for social consumption, it's just that a lot of people are still wary and not frequenting businesses from pubs to shops to gyms as much as they used to. If anything, people are gradually regaining some confidence to do so. I don't think this would be helped by the virus being allowed to run riot again.
I reckon if we are going to get through the winter, with the latest set of reopenings in place plus schools open, we would be doing pretty well indeed.
