My sister in law was in Milan a few days ago. In her words the city was deserted and the reaction by immediate family members to the description was to fuel more panic and suggestions to react by hoarding basic food supplies asap. The main rationale for suggesting that was to react on other people panicking.
It’s especially important to manage your sense of panic when everyone else is losing their mind.
The fact that a simple acknowledgement that hoarding is objectively worse than avoiding large crowds is voted down to -1, should tell you everything you need to know about the sense of panic that is sweeping the internet right now.
Hoarding canned food from your local store hurts everyone, because now they have less food.
