if you're going to cancel events, they should be events with lots of old people, not events where essentially everybody is under 35. so, church services should definitely be cancelled. i'd probably accept them cancelling events at the dso without much pushback.
but, i'd rather see venues put out warnings that tell concert-goers to enter at their own risk.
i'm willing to avoid old folks for a while, but i'd rather catch this thing and beat it than try and hide from it. i'm not afraid of this...
