It depends what you mean by 'back to life as a whole'.
I think the most obvious restrictions, like shops and schools being closed, could well be out of the way by the late summer.
Clearly there will be long-term changes to society as a whole, but we will assimilate them as we go, because that is how society evolves and develops.
I will be happy when - in no particular order -
I can get my hair cut
Go out for an Italian meal
See my friends
See some live music
Go on a cruise.
Anything else, i will deal with when it comes along.
