Life is not black and white as you are trying to make it out to be.
In your mind at least, because covid only affects the old and young and disabled and the poor, it might as well no longer exist.
Not true. I know I could get it and suffer. But I no longer wear masks because the probability of that outcome is low, compared to the 100% probability of inconvenience with wearing a mask (fogging up my glasses, for example - I’ve never been able to stop that problem).
I also know the next time I get into a car, I could be in a very serious life-altering or life-ending crash. But I still ride in cars. Because the odds of a serious crash like that happening are low, and the convenience of riding in a car far outweighs that probability.
Everyone has to gauge their own risk levels for events and decide for themselves what is appropriate.
