No, not really any enormous changes. But here in Sweden we don’t have proper lockdowns (yet), and my office isn’t completely shut dow, we are just strongly recommended to work from home.

If I can confirm that I’ve had it I would start going back to the office (better ergonomics) and start going out on lunches/dates, go to the gym, shop for clothes, meet older relatives etc with (almost) no fear of spreading it to other people.

Assuming immunity, you could take care of your parents, grandparents and other high-risk people. You’d have to balance the risk of a false-positive test and wrong assumptions about immunity against the risk of someone from a high risk group running errands.

You're likely immune, at least for a while. You could live more normally, or join studies, or volunteer and help people out, etc.
