This is nothing new. People with colds and flu could spread their illness by attending such events, and no one blinked an eye. Just as dying in auto, train, and plane accidents is "unfortunate" but not enough to shut down the service.
As far as the motion picture theaters, no thank you. My experience in the typical theater was marred by the patrons who keep talking, popping their chewing gum. and kicking the back of the seat in front of them. Add to that the elimination of the intermission (which I recall fondly when I saw 2001 A Space Odyssey years ago) the prep work for an evening at the movies is more than I can take. Not to mention the $50-60 tab. I have a big screen 4K TV, and use headphones in deference to my upstairs neighbors.
Loved the compartments on the Germany regional trains in the 1980s when stationed there.
