Every so often in the US you’ll hear of people with neuroses that stem from the Great Depression (quite frequently, with hoarding among the elderly population). I think COVID will have a similar impact on a significant subset of the population today.
Sure, the vast majority will move on, but some will continue to live with a vague fear of being too near to other people. Personally, I find this thought very saddening, but I’m bracing myself for it and doing my best to make sure it doesn’t happen to me.
