I think a big lesson of the COVID era is that people care about this kind of thing - statistical mortality - a lot less than you'd expect.
Yes Certainly. For instance if my dad had died of covid the decrease in my quality of life from that would have been permanently effected. Where yours had, your quality of life would be unchanged.
The answer appears to be: to some extent, but there are limits. And I don't think that's new information. People do things all the time that involve some risk to others. They're more careful about risks to themselves and their families, but there are still limits.
Anyone who smokes cigarettes or sometimes drives under the influence (massive numbers of people) already demonstrated that they're willing to inflict much higher degrees of risk on themselves and others than being lax on covid protocols would entail.
