As much as I think that comment was hyperbole, I do hope in future all public places are well ventilated. I took my co2 meter around to trains and planes and there’s so much to improve (esp when boarding).

There’s so much effort put to clean surfaces… wonder how does it compare vs air-born infections. For covid it took so long for hand cleaning mania to go away and masks to come back.

Covid is a deadly disease, and wishing to limit one’s unnecessary exposure to potential infection neither implies nor denotes that one is fearful.

One need not be afraid to avoid unnecessary hazards.

Sigh... It's all a matter of probabilities. I've used and do use public transportation. But only if I absolutely have to. Otherwise I'm minimizing it.

See it the other way around: I'm still unvaxxed! So my reluctance is protecting U ;->
