I think 'hedonic adaptation' (is that the right term?) will probably kick in quite quickly for most people. We all appreciate our health when we get it back after illness, but it's hard to keep that gratitude going consistently for months and years, that's the comparison I'd make.
TBH, I think 'normal life' wasn't that great for a lot of people. I loved my pre-covid life and felt very privileged, but I still remember looking around me one day in late 2019/early 2020 as I exited the station on my way to work. It was packed, everyone shuffling along nose to tail in silence, everyone wearing grey or black, not a splash of colour in sight. "Fuck me, this is Dickensian" I thought to myself.
So I won't be going back to 15 hours a week of commuting on dirty trains, wasting hours of my life on freezing platforms in delays, handing over £1,500 p.a. to a bunch of piss-taking privateer bastards. I won't go back to shopping in supermarkets - it's a time-consuming pain in the butt, especially if you don't drive.
As for the nicer things like bookshops, the pub, galleries, daytrips - yes I am looking forward to these, but I honestly think I might give it a year or so. I don't want to be crowded by tons of people and I want to see how well everything settles down public health-wise. Having had covid last March, (which I almost certainly caught in the office), I am not keen to go out among a load of partially-vaccinated people making hay, I'll leave that to the pensioners for now.
