If I arbitrarily save lives, that's still saved lives. If I arbitrarily reduce the risk of causing harm, that's still reduced risk of harm. Those are good. I value results over consistency. I definitely value results over analysis paralysis, over waiting for a perfection of clarity not available this side of the grave.

And as best I know, I do "do this" with all potentially fatal communicable diseases. I get the flu shot every year. I even do it with non-fatal diseases as best I can. When I'm sick, I stay the hell home. I exercise good hygiene and good food safety.

And I have no idea why people don't do otherwise. All it takes is valuing others' health and survival.
