I know two individuals (that have no major health concerns) that are still living the way they were in March and April 2020. For nearly two years now they have essentially not left their homes, and when they have for essential reasons suit up like they are going into a biohazard.
At this point I don't think folks like that will ever "go back to normal", the last two years have created their current lifestyle as their permanent normal. It's unfortunate.
That's not really surprising. If you think of it as a spectrum, there's going to be people at the biohazard level precautions at one end, and people at the other that never did anything at all, the pandemic didn't really exist for them. Most people are going to fall in the middle somewhere.
I would bet everyone on this thread knows a friend, or friend of a friend, that basically didn't do anything and didn't change any behavior at all. Maybe not quite that far, but some pretty close to that. So, it's not really a surprise to hear about people at the other end too.
Even in my own extended family, we have most of the spectrum covered. From families that have been on many vacations and did only the minimum required by schools, to families that worry about exposures in the week leading up to family events to avoid creating an exposure at the family event. But, most of them fall somewhere in the middle, taking reasonable precautions.
Statistically, more of the ones at the party end have had COVID, but it's not an absolute. Some at the more restrained end have too, just less of them.
Again, most people are going to fall in the middle somewhere, which means we're not going to tell stories about them. They're boring. The super careful and the ultra dismissive, that's where all the "excitement" happens.
