Studies of the way people behaved in the 1920s after the Spanish Flu support this.
There will be some initial reluctance to attend large events, crowds and crowding will feel uncomfortable. There will be a period where people will avoid crowds. I was watching a You Tube of Neil Young playing "Rocking in the New World" at Glastonbury 2009. I was there close to the front, it was rammed I was probably in bodily contact with at least half a dozen complete strangers and didn't think about it. Would I be straight down the front if I could attend an NY gig tomorrow? Probably not? Six months time? Hmmm. Next year? I think so. Behaviour will change, people will wear masks and face coverings for quite a while after the pandemic has swept over us. Some people may be unable to move on but humans don't really change, in a few years time this will just be a scare story we tell our grandkids. Everyone had to stay at home Grandpa? No way...
