I'm 55 and lucky as have a good job I can do from home, but considering the wider picture I think staying home unless necessary is the right thing to do. I do get that it's not a simple decision, but Johnson and co. trying to get people back in the office when they don't need to be is stupidity personified. Same with the schools, a phased week in/week out system would have been better so the schools only ever have 50% capacity at any one time.
One of the issues is people's natural resistance to change. I have long been an advocate of home working but I meet so many luddites who just dismiss it without thinking. I am being simplistic as when I say home working as there are great opportunities to set up local hubs and the likes that keep people distanced, but stop the need for all this commuting and travelling around for meetings and the likes. That's a benefit to the environment and will make people more productive. The coronavirus is a global disaster, but we need to snatch whatever positives we can out of it.
As for lockdown I wish we'd stop using the stupid term, we didn't have a lockdown, we had some restrictions, Spain had a lockdown. For those that found it hard I can empathise, but it was only a few months and if you were furloughed or still working then was it really that bad (NHS and other key workers obviously excepted), I appreciate there will be a good number of edge cases, but overall... well imagine what our grandparents and in some cases parents had to go through in WWII... that was properly hard.
