From The Metro:
Britain could be facing a nationwide curfew as part of efforts to avoid a second wave. People may be banned from going out after 10pm or 11pm to try and keep a lid on the recent surge in cases which has been attributed to younger people socialising.
Venues in Bolton will be required to close between 10pm and 5am to try and halt the transmission of coronavirus there, with a similar curfew also understood to be under consideration in Bradford.
The thinking behind this seems to be that Covid-19 infection rates are now highest among younger people who might have caught it while out in the evening. Quite why they think most of them were infected while socialising after 10pm, rather than doing something else at some other time of the day is unclear.
It's a stupid idea, because younger people are unlikely to become seriously ill and the disease appears to be becoming less virulent anyway. So it's a massive imposition for little return.
And if we are going to do "herd immunity", why not start with children and younger adults? It will go round schools and universities, pubs and clubs like wildfire, so they'll all be immune (for the time being) and then hopefully the oldies will be less likely to catch it later on (having kept their heads down for another six months).
