> I wonder how much climate has anything to do with it. I'm going to opine that climate in SF helps a lot. I've lived in SF 25 years. All summer the uniform is long sleeve shirt w/under shirt. Light jacket for evenings/outings. Light to moderate wind. Only a week or so of hot/90F temperatures. It's turning toward winter now, so we're adding a sweater and water-resistant jacket. Moderate winds. I've never needed a down coat. In other words, we can pretty easily socialize outside and/or keep windows open, so any Covid virus tends to quickly disperse.
