As callous as it sounds, I don’t think doing things for “any improvement” means it is worth doing. Everything has a cost/benefit ratio. Are you going to wear a mask for the rest of your life in public and private (your household matters too) because you could catch the flu or someone could catch it from you? Are you going to stay out of motor vehicles because they could injure you or someone else?

People have become so extreme in their views that every single life matters that they forget how our 2019 way of life still had significant risk that nobody batted an eye at.
