Actually don’t have a problem with them acting normal during this.
First, its been way overhyped. pH should retargeted to measure panic/Hysteria. Just taking normal flu precautions would be fine for almost everyone. High risk folks could help themselves out further by limiting unnecessary exposures to other people.
Second almost none of them are in any high risk demographic for this or the flu, unless they somehow fall into the “infirm” category.
They aren’t really in the high risk category.
