Would you be in favour of a January or February lockdown ever year?

Obviously not enforced by law but just a general agreement that we can stay at home in our pyjamas for a month and not have to go to meetings or out and about at all unless we really wanted to.

 

I would.

part from work meetings, you could do that anyway

Yeah, that is the key thing stopping me - being in the office occasionally and work meetings, events.  Also provides excuse for turning down social invitations - essentially I would like to hibernate for a month each year.
