It would be a thousand A/B tests, because there was no one "covid measure". Individual measures like wearing n95s in crowded areas like stores make sense, but not allowing music at gyms is stupid. My childrens' school is still on full lockdown. They are wearing masks outside and must keep distance from each other. And all students are fully vaccinated. Makes no sense.
